Create Search API like itunes Search API using PHP and MySQL

                      The Apple itunes provided a search API for retrieve app information from it. The Apple search API display result as JSON format. Do you want to know more information about Apple itunes search API, then visit iTunes Search API.

                      You can also create search API like Apple itunes search API if you know how to create JSON file using PHP. Due to this, you can provide search API for your websites. If you didn't know create JSON file using PHP and MySQL, then visit How to get output as JSON format using PHP and Mysql.

Generate Search API using PHP and MySQL

                       Lets see how to create search API using PHP.  Follow below steps to generate search API for your websites using PHP.

Step1: Connect MySQL database using PHP

                     Connect your MySQL database to get stored values from it using PHP. The PHP code for connect MySQL database is below:

 mysql_connect('localhost','root','') or die(mysql_error());
 mysql_select_db('fitness') or die(mysql_error());

Step2: Get value from url using PHP

                     While user search something on your search API, you need to get those values for search from url. So only you can provide particular results from your MySQL database. This is done by below PHP code.

 $field=$_REQUEST['field'];
 $limit=$_REQUEST['limit'];

Step3: Make MySQL select query

                     After got values from url, you've to make MySQL query to select corresponding results from database. You can get zero or more than one values from urls for search. You should make MySQL query like below using PHP.

 if($field!='' && $limit!='')
 {
   $cond="where name='".$field."' order by id desc limit 0, $limit";
 }
 if($field=='' && $limit!='')
 {
   $cond="order by id desc limit 0, $limit";
 }
 if($field!='' && $limit=='')
 {
   $cond="where name='".$field."' order by id desc limit 0, 50";
 }
 if($field=='' && $limit=='')
 {
   $cond="order by id desc limit 0, 50";
 }
 $q=mysql_query("select * from f_img $cond") or die(mysql_error());

Step4: Add header for get output as JSON format

              You must add header type ato your PHP script for get output as JSON format. This is like below

 header('Content-Type: Application/json');

Step5: Add content to JSON file using PHP

               You need to create 2 array for create output as multidimensional array. Retrieve values from query result using mysql_fetch_array. Then you push values to array using array_push() in PHP. Finally encode the results to display output as JSON format using json_encode().

               The full PHP code for create search API is represented below,

<?php
 error_reporting('E_ALL ^ E_NOTICE');
 mysql_connect('localhost','root','') or die(mysql_error());
 mysql_select_db('fitness') or die(mysql_error());
 $field=$_REQUEST['field'];
 $limit=$_REQUEST['limit'];
 if($field!='' && $limit!='')
 {
   $cond="where name='".$field."' order by id desc limit 0, $limit";
 }
 if($field=='' && $limit!='')
 {
   $cond="order by id desc limit 0, $limit";
 }
 if($field!='' && $limit=='')
 {
   $cond="where name='".$field."' order by id desc limit 0, 50";
 }
 if($field=='' && $limit=='')
 {
   $cond="order by id desc limit 0, 50";
 }
 $q=mysql_query("select * from user $cond") or die(mysql_error());
 header('Content-Type: Application/json');
 $details=array();
 $user=array();
 while($res=mysql_fetch_array($q))
 {
  $user['name']=$res['name'];
  $user['state']=$res['state'];
  $user['country']=$res['country'];
  array_push($details,$user);
 }
 //print_R($details);
 echo json_encode($details);

?>

           Your JSON output should be like below,

[
 {"name":"Clark","state":"California","country":"USA"},
 {"name":"Anderson","state":"Los Angeles","country":"USA"},
 {"name":"Smith","state":"London","country":"United Kingdom"},
 {"name":"Jones","state":"Cambridge","country":"United Kingdom"},
 {"name":"Nathan","state":"Franche Comte","country":"France"},
 {"name":"Marie","state":"Paris","country":"France"},
 {"name":"Nastya","state":"St Petersburg ","country":"Russia"},
 {"name":"Dima","state":"Moscow","country":"Russia"},
 {"name":"Linh","state":"Hanoi","country":"vietnam"},
 {"name":"Hoang","state":"Hai Phong","country":"vietnam"},
]

Step6 : .htaccess

                   Add following lines to your .htaccess file

RewriteRule ^search search.php [L]

                  Now you entered search on address bar, the .htaccess redirects you to search.php file. You can get search API using below url types.

                http://www.phponwebsites.com/search?field=nathan&limit=10
                http://www.phponwebsites.com/search?field=nathan
                http://www.phponwebsites.com/search?limit=10
                http://www.phponwebsites.com/search

Create XML file using PHP and MySQL

                                   You can get output as XML format using PHP. You can import values to XML file from Mysql database using PHP.

                                   XML expands Extensible Markup Language. It is used to share your data across various platforms. You can also retrieve values from XML file using PHP.

Get output as XML format using PHP

                                    If you want to convert your Mysql table values into XML format using PHP, then follow below steps.

Step1: Add header to XML file in PHP

                                    First you need to add content type of XML file in PHP in order to get output as XML format. It need to add below PHP codes in your PHP file.

header ("content-type: text/xml");

Step2: Connect mysql database

                                    After added content type of XML, you need to connect Mysql database using PHP to retrieve values from it. You add below codes after content type in PHP file.

mysql_connect('localhost','root','');
mysql_select_db('fitness');

Step3: Add content to XML file

                                  Then select required values from Mysql database using mysql_query(). Retrieve values from query result using mysql_fetch_array. Finally your PHP file look likes below one.

<?php
header ("content-type: text/xml");
mysql_connect('localhost','root','') or die(mysql_error());
mysql_select_db('fitness') or die(mysql_error());
$xml='<?xml version="1.0" encoding="UTF-8"?>';
$qr=mysql_query("SELECT * FROM `f_img` order by id desc") or die(mysql_error());
$xml.='<userlist>';
while($res=mysql_fetch_array($qr))
{
 $xml.='<user><name>'.$res['name'].'</name><state>'.$res['state'].'</state><country>'.$res['country'].'</country></user>';
}
$xml.='</userlist>';
echo $xml;
?>

                                 You will get output as XML format like below,

<userlist>
    <user>
       <name>Clark</name>
       <state>California</state>
       <country>USA</country>
   </user>
   <user>
      <name>Smith</name>
      <state>London</state>
      <country>United Kingdom</country>
   </user>
   <user>
      <name>Nathan</name>
      <state>Franche Comte</state>
      <country>France</country>
   </user>
   <user>
      <name>Nastya</name>
      <state>Moscow</state>
      <country>Russia</country>
   </user>
</userlist>

                                     Now you got output as XML content. Similarly, you can get XML element's values using PHP.

Create json file using PHP and MySQL

                        You can create json file using PHP and Mysql. You can get output as json format using PHP and Mysql. Before you want to know that, first you should know what is json? and what is the us of json?

JSON

      
                       JSON expands JavaScript Object Notation. It is one of the data interchange format. You can easily read and write data through JSON file.

                       It is language independent. So you can retrieve data from it using any familiar languages like PHP. It should be array format, object format and both array and object fotmat.

     The array format of Json file should be like this,

       [    
           {
              'tutorial':'PHP',
              'link':'http://www.phponwebsites.com/p/php.html'
           },
           {
              'tutorial':'Mysql',
              'link':'http://www.phponwebsites.com/p/mysql.html'
           },
           {
            'tutorial':'htaccess',
            'link':'http://www.phponwebsites.com/p/htaccess.html'
           }    
      ]

The object of JSON should be like this,

    {  
           'tutorial':'PHP',
            'link':'http://www.phponwebsites.com/p/php.html'  
    }

Get output as json format using PHP and Mysql

                           Now you know something about JSON files. So we are going to know how to get output as JSON format using php and mysql.

Add header to create json file using PHP and Mysql

       
                          If you want to create json file, then you have to add header for json file. It is like below

header('Content-Type: application/json'); 

          Where json indicate this is json file

Add content to json file using PHP

             Then you need to add contents to your json file as you want as. Retrieve values from query result using mysql_fetch_array. Suppose you have more values in a variable. Then you need to store all values in array. Consider the following PHP code.

<?php
header('Content-Type: application/json');
$linklist=array();
$link=array();
mysql_connect('localhost','root','') or die(mysql_error());
mysql_select_db('quicksai_quick') or die(mysql_error());
$qr=mysql_query("SELECT * FROM `links` ") or die(mysql_error());
while($res=mysql_fetch_array($qr))
{
 $link['tutorial']=$res['tutorial'];
 $link['url']=$res['url'];
 array_push($linklist,$link);
}
//print_R($linklist);
echo json_encode($linklist);
?>

      The above example explain how to create json file on multidimensional array using PHP and Mysql.
     where,
               array() - create array variable.
               array_push() - insert values into array
               json_encode() - encode the values and returns JSON representation of values
             

The above example will give output as json file. It should be like this:

      

      [

      {'tutorial':'PHP', 'link':'http://www.phponwebsites.com/p/php.html'},

      {'tutorial':'Mysql', 'link':'http://www.phponwebsites.com/p/mysql.html'},

      {'tutorial':'htaccess','link':'http://www.phponwebsites.com/p/htaccess.html'}

      ]

  

                   Now you can get output as json file. Then you should know how to retrieve values from json file using PHP.

Generate RSS Feed dynamically using PHP and MySQL

                 Let see how to create RSS Feed dynamically using PHP and MySQL. Follow the below steps to create feed.

1. Create database and table

                  First you create database for store your link details on it. The below MySQL query is used for create database.

                Create database new

 where new is database name

                Use new

The above query is used to use database "new".
                  The MySQL query for create table is,

                Create table links (id int not null auto_increment primary key, name varchar(200), link varchar(200), description varchar(250))

                 Now the table "links" is created. Then store values into table using below query

                insert into table links values('','PHP','http://www.phponwebsites.com/p/php.html','PHP doubts are clarified at Phponwebsites')

                After insert values into table, your table look likes below

2. Add header type RSS Feed

                            First you need to add content type of RSS feed. It is represented below.

header("Content-Type: application/rss+xml; charset=ISO-8859-1");

3. Add content to RSS Feed

                         
                            First of all you need to store all links in your database. Then on;y you can retrieve it using PHP. The below example we Retrieve data from MySQL database using mysql_fetch_array in PHP.
After added header, you have to add some name spaces for RSS Feed. Finally add contents to RSS Feed.

<?php
header("Content-Type: application/rss+xml; charset=ISO-8859-1");
echo '<?xml version="1.0" encoding="UTF-8" ?>

       $connection = @mysql_connect('localhost', 'root', '') or die(mysql_error());
       mysql_select_db('new')  or die (mysql_error());
       $query = "SELECT * FROM links order by id desc";
       $rss = mysql_query($query) or die (mysql_error());
       $ImgPath='https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiwiEMDL1tvD_oaHIph6KkufjJK5hc5m7kwdJoVgkjFJuf4oqWWbSQXNDkuq1-ukdOhgudTe6gou7Al4oAbvJ-oC-ejuZEhre-ue99v02aajGkKGacaDkZPfk09v7DvUzZlJbIoaxNajoMu/s1600/logo5.png';
       while($row=mysql_fetch_array($rss)){
       echo '
<item>
<title>'.$row['name'].'</title>
<link>'.$row['link'].'</link>
<content:encoded>
      <![CDATA[<p align="left">
          <a href="'.$row['link'].'"><img style="background-image: none; " border="0" src="'.$ImgPath.'" />    </a></p>]]>
       </content:encoded>
       <description>'.$row['description'].'</description></item>';
}
      echo '</channel>
</rss>';
?>

               When you run this file on firfox, you will get output like below

4. Htaccess

                         Then you have to add below lines to your htaccess file.

                    RewriteRule ^rss.xml$ rss.php [L]

When you type rss.xml in your browser address bar, it redirects to rss.php.

             Finally you got dynamic RSS Feed.

<?php

    mysql_connect('localhost','root','') or die(mysql_error());

    mysql_select_db('new')  or die(mysql_error()); 

    $q=mysql_query('select * from stats where date IN (CURDATE())')  or die(mysql_error());

    $n=mysql_num_rows($q);

    if($n==0)

    {

     mysql_query("insert into stats values(1,CURDATE())");

    }

    else

    {

     mysql_query("update stats set view=view+1 where date IN (CURDATE())");

    }

?>

where,
      - select * from stats where date IN (CURDATE()) is select the views if present in current date.
      - mysql_num_rows() return the number of rows selected. If it is 0, then value inserted into mysql table. Otherwise values are updated.

3. Stats(chart) using php and mysql:

                    Then you need to create statistics using php and mysql through google charts. There are many types of charts in google. You can choose anything as you want. The php code for create stats:

daily_stats.php

<html>
<body>
<?php
    mysql_connect('localhost','root','')  or die(mysql_error());
    mysql_select_db('new') or die(mysql_error());
?>
    <script type="text/javascript" src="https://www.google.com/jsapi"></script>
    <script type="text/javascript">
      google.load("visualization", "1", {packages:["corechart"]});
      google.setOnLoadCallback(drawChart);
      function drawChart() {var data = google.visualization.arrayToDataTable([
 <?php
$str=" ['Day', 'Day'] ";
$query="select view as vi, DATE_FORMAT( date, '%b-%d' ) as dat from stats order by date ASC";
$result=mysql_query($query)  or die(mysql_error());
while($rows=mysql_fetch_array($result,MYSQL_BOTH)){
$str =$str . ",['". $rows['dat'] ."'," .$rows['vi'] ."]" ;
}
echo $str;
?>
        ]);

      var options = {
          //title: 'Company Performance',
          hAxis: {title: 'Day', titleTextStyle: {color: 'red'}},
          vAxis: {title: 'Total views', titleTextStyle: {color: '#FF0000'}, maxValue:'5', minValue:'1'},
        };

        var chart = new google.visualization.ColumnChart(document.getElementById('chart_div'));
        chart.draw(data, options);
      }
    </script>        
   <p style="font-size:20px;">Dialy Stats</p>
   <div id="chart_div" style="width: 400px; height: 200px;"></div>
</body>
</html>

where,    
               The following MySQL query is used to find total number of views of your websites per daily
        - select view as vi, DATE_FORMAT( date, '%b-%d' ) as dat from stats order by date ASC
is select the number of views daily.

var chk = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;
if(name=='')
{
 $('#er').html('Enter your name');
 return false;
}
if(password=='')
{
 $('#er').html('Enter your password');
 return false;
}
if(mail=='')
{
 $('#er').html('Enter your mail');

Create excel spreadsheet using PHP and Mysql

                       You can generate excel spreadsheets easily using PHP. You need to follow below steps to create excel file.

Add content type:

                    First you need to add excel sheet content type to create excel file using PHP.

header("Content-Type: application/vnd.ms-excel");

Add name and download excel file:

                    You can provide name for excel spreadsheet and make your sheet as downloadable file on coding. The Content-Disposition is used to force browser to save a file. For that, your file should be attached following line:

header("Content-disposition: attachment; filename=spreadsheet.xls");

Add content to excel spreadsheet:

                   Finally you can add contents to your excel file. Consider the following PHP script for generate excel file:

<?php
header("Content-Type: application/vnd.ms-excel");
header("Content-disposition: attachment; filename=spreadsheet.xls");
mysql_connect('localhost','root','') or die(mysql_error());
mysql_select_db('new') or die(mysql_error());
$q=mysql_query("select * from table1")  or die(mysql_error());
if(mysql_num_rows($q)>0)
{
echo"<table><tr><th>Name</th><th>Address</th><th>Phone</th></tr>";
 while($res=mysql_fetch_array($q))
 {
  echo"<tr><td>".$res['name']."</td><td>".$res['address']."</td><td>".$res['phone']."</td></tr>";
 }
echo"</table>";
}
?>

     Where,
                 mysql_fetch_array() return values as both an associative and numeric array.

Remember me in login form using php:

                     Consider the following example. You have 3 php pages such as login.php, welcome.php and signout.php.

login.php:

<html>
<head>
<style type="text/css">
 input{
 border:1px solid olive;
 border-radius:5px;
 }
 h1{
  color:darkgreen;
  font-size:22px;
  text-align:center;
 }
span{
  color:lightgreen;

 }
</style>
</head>
<body>
<h1>Login<h1>
<form action='#' method='post'>
<table cellspacing='5' align='center'>
<tr><td>User name:</td><td><input type='text' name='name'/></td></tr>
<tr><td>Password:</td><td><input type='password' name='pwd'/></td></tr>
<tr><td></td><td><input type='checkbox' name='remember' /> <span>Remember me</span></td></tr>
<tr><td></td><td><input type='submit' name='submit' value='Submit'/></td></tr>
</table>

</form>
<?php
session_start();
//your values are stored in cookies, then you can login without validate
if(isset($_COOKIE['name']) && isset($_COOKIE['pwd']))
{
    header('location:welcome.php');
}
// login validation in php
if(isset($_POST['submit']))
{
 mysql_connect('localhost','root','') or die(mysql_error());
 mysql_select_db('new') or die(mysql_error());
 $name=$_POST['name'];
 $pwd=$_POST['pwd'];
 if($name!=''&&$pwd!='')
 {
   $query=mysql_query("select * from login where name='".$name."' and password='".$pwd."' ");
   $res=mysql_fetch_row($query);
   if($res)
   {
    if(isset($_POST['remember']))
{
 setcookie('name',$name, time() + (60*60*24*1));
 setcookie('pwd',$pwd, time() + (60*60*24*1));
}
    $_SESSION['name']=$name;
    header('location:welcome.php');
   }
   else
   {
    echo'You entered username or password is incorrect';
   }
 }
 else
 {
  echo'Enter both username and password';
 }
}
?>
</body>
</html>

             where,
            if(isset($_COOKIE['name']) && isset($_COOKIE['pwd'])) {} means if the user values in  cookies, then the user can login directly without login validation in php.
         
           if(isset($_POST['remember'])){
           setcookie('name',$name,time() + (60*60*24*1));
           setcookie('pwd',$pwd,time() + (60*60*24*1));
           }
           which means, if the user click the remember me check box, then you have to store them in cookie. If you don't know  about cookies in php, then visit Cookies in php.

          When you run the login.php fille, you'll get output like this:

welcome.php:

<?php    
  session_start();
  if(isset($_COOKIE['name']))
  {
    echo 'Welcome: '. $_COOKIE['name'].'<br>';
  }
  else
  {
    echo 'Welcome: '. $_SESSION['name'].'<br>';
  }
  echo'<a href="signout.php">Singout</a>';
?>

      where,
                  if(isset($_COOKIE['name'])){}else{} means if the values in cookie, then return name from cookie. Otherwise name return from session.

             Now you enter username and password  'guru' and 'guru' without select the remember check box, you will navigate to 'welcome.php' page and get output like this:

                   welcome: guru
                   Signout

 If it is wrong, then you can't login.

   

Signout in php:           

            When you click the signout.php, it destroy the session and return back to login page. The php script for signout page:
signout.php:

<?php    
         session_start();
         session_destroy();
         header('location:login.php');
?>

           You select the remember me check box while login. Then you navigate to welcome.php page. Now you click the signout on welcome.php page, you can't return back to login page. Because the concept is, when you signout the page, you return back to login.php page, where you wrote the php script as like as:

          
                  if(isset($_COOKIE['name']) && isset($_COOKIE['pwd'])) {}

It means, if values in cookie, you can login again. Now you comes to login page and again login and navigates to welcome page because your values in cookies.So you are in welcome page until the cookie is expired.

Structure of sitemap: 

                    The structure of sitemap is:

<?xml version="1.0" encoding="UTF-8">
 <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9
 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd">
  <url>
    <loc>http://www.phponwebsites.com</loc>
<lastmod>today date<lastmod>
<changefreq>daily</changefreq>
<priority>1</priority>
  </url>
  <url>
    <loc>http://www.phponwebsites.com/p/htaccess.html</loc>
<lastmod>today date<lastmod>
<changefreq>daily</changefreq>
<priority>1</priority>
  </url>
 </urlset>

  where,
      urlset - encapsulates the file ie, start sitemap
      url - parent tag for each entry ie, each page
      loc - location of url
      lastmod - date for last modification of file
      changefreq -  how frequently the pag is changed. It should be always, hourly, daily, monthly, weekly, yearly, never
      priority - priority of url. It should be between 0.0 to 1.0

Create sitemap dynamically using PHP and MySQL:

                          First you need to add content type for xml to generate sitemap in PHP. ie,

 header ("content-type: text/xml");

                        Then add contents to XML file. Then save this file as sitemap.php .

<?php
 mysql_connect('localhost','root','') or die(mysql_error());
 mysql_select_db('new') or die(mysql_error());
 $dat=date('Y-m-d');
 header ("content-type: text/xml");
 echo '<?xml version="1.0" encoding="UTF-8"?>
 <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9
 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd">';
 $urls=mysql_query("select * from url")or die(mysql_error());
 while($row_Tags=mysql_fetch_array($urls))
 {
   echo "<url><loc>".$row_Tags['url']."</loc><lastmod>".$dat."</lastmod><changefreq>daily</changefreq><priority>1</priority></url>";
 }
  echo "</urlset>";
 ?>

.htaccess:

               

               In your .htaccess, you add following codes.

RewriteRule ^sitemap.xml sitemap.php [L]

                   When you run sitemap.xml on your website each time,  it display upto date contents.
