PHP get particular key value from multidimensional array

You can get specific key from multidimensional array using any one of the below methods:

1. Get Specific key value form multidimensional array using array_column:

The array_column() returns the values from a single column in the input array. It works only from PHP version 5.5. You've a multidimentional array with details of user name and country. You tried to get the name of every array from multidimentional array. Consider the following exampale:

<?php

$array = array(
0 => array(
'name' => 'Guru',
'country' => 'India'
),
1 => array(
'name' => 'Clark',
'country' => 'USA'
),
2 => array(
'name' => 'Smith',
'country' => 'United Kingdom'
),
3 => array(
'name' => 'John',
'country' => 'USA'
),
);

$namesArray = array_column($array, 'name');
print_r($namesArray);exit;

When you run this program in the browser, you will get the output like below one:

Array ( [0] => Guru [1] => Clark [2] => Smith [3] => John )

For more details about array_coulmn, visit http://php.net/manual/en/function.array-column.php.

2. Get Specific key value form multidimensional array using array_map:

The array_map() applies the callback to the elements of the given arrays. It works from PHP version 4.0.6. The array_map() is alternate of array_column() in PHP

<?php
$namesArray = array_map(function($arr){
return $arr['name'];
}, $array);
print_r($namesArray);exit;

It will give same output as array_column. For more details about array_map, visit http://php.net/manual/en/function.array-map.php.

3. Get Specific key value form multidimensional array using foreach loop:

<?php
$namesArray = array();
foreach($array as $key => $val) {
$namesArray[] = $val['name'];
}
print_r($namesArray);exit;

It will also give sample output as array_coulmn & array_map.

Now I've hope you know how to get particular key value from multidimensional array in PHP.

Find prime numbers between 1 and 100 in PHP

This blog describes how to find prime numbers between 1 and 100 using PHP. Prime number is a number which is divided by 1 and itself. Consider the number 5. It is prime number because it can be divided by 1 and 5.

PHP program for prime numbers:

Consider the below program which is used to find prime numbers from 1 to 100.

<?php
    for($i = 1; $i <= 100; $i++)
      $mm = 0;
      for($j = 2; $j <= $i/2; $j++) {
        //only not prime numbers
                if ($i % $j == 0) {
                $mm++;
                break;
                }
      }
      if ($mm == 0) {
                echo"$i is prime number<br/>";
      }
    }
?>

In above program, if a number is divided by any number except 1 and itself, then it is not prime number. Otherwise it is a prime number.

PHP program for find prime numbers from a to 100

Now you got prime numbers between 1 and 100 using PHP.

Consider below example which is find Armstrong Numbers between 1 to 1000.

<?php
for($i = 1; $i <= 1000; $i++) {
$sum = 0;
$qu = $i;
while($qu != 0) {
$remainder = $qu % 10;
$thrice = $remainder * $remainder * $remainder;
$sum += $thrice;
$qu = $qu / 10;
}
if ($sum == $i) {
echo "<p>$i is armstrong number</p>";
}
}
?>

Now you got Armstrong Numbers between 1 to 1000.

Fibonacci series of given number in PHP

This blog describes about how to find Fibonacci series of given number in PHP. Fibonacci series is a sequence of number generated by adding previous two numbers. If the given number is 'n', then Factorial of 'n' is defined as 'Fn'. In mathematical terms, Fibonacci series for 'n' number looks like this:

Fn = Fn-1 + Fn-2;

Where,
F0 = 0;
F1 = 1;

Fibonacci series for 'n' number is calculated recursively by above formula.

Simple PHP program Fibonacci series:

This is the simple PHP program for find Fibonacci series.

function fibonacci_series($n) {
$f1 = -1;
$f2 = 1;

for ($i = 1; $i <= $n; $i++) {
$f = $f1 + $f2;
$f1 = $f2;
$f2 = $f;
echo "$f<br />";
}
}

echo fibonacci_series(5);

The above PHP program returns 0, 1, 1, 2, 3. As i said, Fibonacci series is a sequence of number generated by adding previous two numbers. In above program, we have generated Fibonacci series for 5.
We have assumed $f1 = -1; and $f2 = 1; We need to run for loop until 5.As per above program,

If $i = 1:
$f = -1 + 1 = 0;
$f1 = 1;
$f2 = 0;

If $i = 2:
$f = 1 + 0 = 1;
$f1 = 0;
$f2 = 1;

If $i = 3:
$f = 0 + 1 = 1;
$f1 = 1;
$f2 = 1;

If $i = 4:
$f = 1 + 1 = 2;
$f1 = 1;
$f2 = 2;

If $i = 5:
$f = 1 + 2 = 3;
$f1 = 2;
$f2 = 3;

Fibonacci series for 'n' number in PHP:

The below PHP program is used to find Fibonacci series of given number.

Factorial of given number in PHP

This blog describes about how to find factorial of given number in PHP. The factorial is one of the maths concept. It is multiplication of numbers from 1 to given number. If the given number defined as 'n', then 'n' factorial represented as 'n!'. The factorial formula for 'n' number looks like:

n! = 1 * 2 * 3 ... n;

For example, the factorial of 5 looks like this:

5! = 1 * 2 * 3 * 4* 5 = 120;

Simple PHP program for Factorial:

Consider the below example which is the sample PHP program for find factorial of number:

function factorial($a) {
$fact = 1;
for($i = 1; $i <= $a; $i++) {
$fact = $fact * $i;
}
return $fact;
}
$f = factorial(4);
echo $f;

Where,
'n' is 4.
n! = 4! = 1 * 2 * 3 * 4 = 24.

Factorial for 'n' number in PHP:

Consider the below example which is the PHP program for find factorial of given number. For example, if you enter 4, it will return factorial of 4. Like if you enter 'n' number, it will return factorial of 'n'.

Ajax upload file or image in PHP using jQuery

You can upload files and images using PHP. Basically it can be uploaded by form submitting. For more details visit how to upload file or image using PHP. When i tried to upload images using Ajax with jQuery, i can't get it work. All of you may be face this problem. This blog describes how to upload file or image in PHP using jQuery with Ajax.

Consider the following example for upload files using Ajax and PHP.

Html form for upload image:

To upload file or image, your html form should be like below form:

<form name="multiform" id="multiform" action="#" method="POST" enctype="multipart/form-data">
Image : <input type="file" name="file" id="file" /></br>
<input type="button" id="multi-post" value="Upload"></input>
</form>

where,
enctype="multpart/form-data - must be present in form. Otherwise file does not upload.
type="file" in <input> tag is used to take input as a file.

Ajax and jQuery for upload image:

Before add Ajax code to your html file, you need to add jquery-1.7.2.min.js library file. To upload image, you have to write Ajax code like below:

$(document).ready(function(){

$("#multiform").submit(function(e) {

var formObj = $(this);

if(window.FormData !== undefined) {

var formData = new FormData(this);

$.ajax({

url: 'upload.php', //url to process the sent data

type: 'POST', //form type

data: formData, //form data to send

mimeType:"multipart/form-data", //type of form data

contentType: false, //content type of form

cache: false, //disable cache the request page

processData: false, //to send DOMDcoument or non processed data file

success: function(data, textStatus, jqXHR) {

$("#er").html(data);

error: function(jqXHR, textStatus, errorThrown) {

$("#er").html('textStatus=' + textStatus + ', errorThrown=' + errorThrown);

}

});

//reset file field after form submitted

$('#file').val('')
//prevent the page is refreshed

e.preventDefault();

//e.unbind();

}

});

$("#multi-post").click(function() {

//submit the form and send data

$("#multiform").submit();

});

When user click the upload button, the form is submitted, ajax is called and send form data as well.

Html file with Ajax for upload image:

We need to combine html form and ajax code to make a full html file for upload file or image. You may add some styles to html file in order to give attractive presence to users. After combined above all things, your html code should be like below one:

upload-ajax.html:

<html>

<head>

body {

color:white;

font-size:14px;

}

.contact {

text-align:center;

background: none repeat scroll 0% 0% #8FBF73;

padding: 20px 10px;

box-shadow: 1px 2px 1px #8FBF73;

border-radius: 10px;

width:520px;

}

#file {

width: 250px;

margin-bottom: 15px;

background: none repeat scroll 0% 0% #AFCF9C;

border: 1px solid #91B57C;

height: 30px;

color: #808080;

border-radius: 8px;

box-shadow: 1px 2px 3px;

padding: 3px 4px;

}

#multi-post

{

background:none repeat scroll 0% 0% #8FCB73;

display: inline-block;

padding: 5px 10px;

line-height: 1.05em;

box-shadow: 1px 2px 3px #8FCB73;

border-radius: 8px;

border: 1px solid #8FCB73;

text-decoration: none;

opacity: 0.9;

cursor: pointer;

color:white;

}

#er {

color: #F00;

text-align: center;

margin: 10px 0px;

font-size: 17px;

}

</style>

</head>

<body>

$(document).ready(function(){

$("#multiform").submit(function(e) {

var formObj = $(this);

if(window.FormData !== undefined) {

var formData = new FormData(this);

$.ajax({

url: 'upload.php',

type: 'POST',

data: formData,

mimeType:"multipart/form-data",

contentType: false,

cache: false,

processData:false,

success: function(data, textStatus, jqXHR) {

$("#er").html('<pre><code>'+data+'</code></pre>');

error: function(jqXHR, textStatus, errorThrown) {

$("#er").html('textStatus=' + textStatus + ', errorThrown=' + errorThrown);

}

});

$('#file').val('')

e.preventDefault();

//e.unbind();

}

});

$("#multi-post").click(function() {

//sending form from here

$("#multiform").submit();

console.log();

});

</script>

<h1>Upload files using Ajax and PHP</h1>

Image : <input type="file" name="file" id="file" /></br>

</form>

</div>

</body>

</html>

When you view the upload-ajax.html in browser, it should be like below image:

How to upload images using PHP, and Ajax with jQuery

PHP snippet for upload file:

When ajax is called, url which is in ajax call received form data. Then the file or image is to be uploaded using following PHP code.

upload.php:

<?php

$file=$_FILES['file']['name'];

if($file!='')

{

//upload file

move_uploaded_file($_FILES['file']['tmp_name'],$_SERVER['DOCUMENT_ROOT'].'/test/uploaded_img/'.$file);

//check whether file is exists or not in a folder

if(file_exists($_SERVER['DOCUMENT_ROOT'].'/test/uploaded_img/'.$file)) {

echo'Uploaded successfully';

}

else {

echo'File is not uploaded';

}

Where,

move_uploaded_file() - used to upload the file

file_exists() - used to check whether the file is already exists in a folder or not after upload the file

$_SERVER['DOCUMENT_ROOT'] - used to represent the directory

Now you can add either file or image using PHP and jQuery with Ajax.

Upload multiple files/images using PHP

You can upload single file and image easily in PHP. Now we are going to know how to upload multiple files and images using PHP. You can upload more than one images or files at the time using PHP. It can done using by array concepts.

Form for upload multiple images:

First you need to make form for upload more images. Your form should be like following:

You should add enctype="multipart/form-data" for upload files. You can see above where the name of file tag should be array like name="file[]" for store multiple values.

Upload multiple images using PHP:

Similarly upload single image, you will get image values by $_FILES['file']['name'] in PHP while submitting a form. You need temporary name of image to pass one of the parameter in move_uploaded_file() in order to upload files. If you've a single image, then you can upload easily by move_uploaded_file($_FILES['file']['tmp_name'],$name). But you need to upload multiple images. So you've to get values as an array. Then upload each image using loop. Consider the following example. Here it describes how to get temporary name of each image one by one using loop in PHP.

<?php
if(isset($_POST['submit']))
{
$name=$_FILES['file']['name'];
foreach($name as $val => $name1)
{
$file_name=$name1;
$tmp=$_FILES['file']['tmp_name'][$val];
move_uploaded_file($tmp,$_SERVER['DOCUMENT_ROOT'].'img/'.$file_name);
}
}

?>
<html>
<body>
<form action="#" method="post" enctype="multipart/form-data">
<table>
<tr><td><input type="file" name="file[]" id="file" multiple="multiple"></td></tr>
<tr><td><input type="file" name="file[]" id="file" multiple="multiple"></td></tr>
<tr><td><input type="submit" id="submit" name="submit" value="submit"></td></tr>
</table>
</form>
</body>
</html>

Where,
move_uploaded_file() - to upload files to desired location.
$_SERVER['DOCUMENT_ROOT'] gives the root directory of current script executing.
You can upload multiple files as well as images using this PHP script.

$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
