Pagination using php and mysql

                       Pagination in php is very simple concepts. You can learn easily. Just follow the below steps.

      1. Find the Start values based on page number:


 $limit=10;
 $page=$_GET['p'];
 if($page=='')
 {
  $page=1;
  $start=0;
 }
 else
 {
  $start=$limit*($page-1);
 }

     Where,
                  $limit is the number rows per page.
                  $page is page number.
                  $start is starting point of limit in mysql query.
If the page number is 1, then the start is 0 which is find by $start=$limit*($page-1).
                  $start=10*(1-1)
                  $start=10*(0)
                  $start=0
                 
If the page number is 2, then the start is 10.
Similarly, if the page number is 3, then the start is 20.

                    2. Find total number of records in mysql table:

Then we need to calculate the total number of data in table. Then find the maximum pages using php script like below:

$tot=mysql_query("SELECT * FROM table1")  or die(mysql_error());
$total=mysql_num_rows($tot);
$num_page=ceil($total/$limit);


     Where,
                mysql_num_rows() returns the numbers results in numeric.
                ceil() returns the whole digit number. ie, ceil(2.3) => 3.
                $maxpage returns the number of pages.


                     3. Function for pagination:

        The php script for pagination function is:

function pagination($page,$num_page)
{
  echo'<ul style="list-style-type:none;">';
  for($i=1;$i<=$num_page;$i++)
  {
     if($i==$page)
{
 echo'<li style="float:left;padding:5px;">'.$i.'</li>';
}
else
{
 echo'<li style="float:left;padding:5px;"><a href="pagination.php?p='.$i.'">'.$i.'</a></li>';
}
  }
  echo'</ul>';
}     

           Where,
                        You need to use for loop for display number of pages in mysql table.


                       4.The whole php code for pagination as follows as:

<?php
error_reporting('E_ALL ^ E_NOTICE');
mysql_connect('localhost','root','')  or die(mysql_error());
mysql_select_db('new')  or die(mysql_error());
$page=$_REQUEST['p'];
$limit=10;
if($page=='')
{
 $page=1;
 $start=0;
}
else
{
 $start=$limit*($page-1);
}
$query=mysql_query("select * from table1 limit $start, $limit") or die(mysql_error());
$tot=mysql_query("select * from table1") or die(mysql_error());
$total=mysql_num_rows($tot);
$num_page=ceil($total/$limit);
echo'<table><th>Reg.Id</th><th>Name</th><th>Category</th>';
while($res=mysql_fetch_array($query))
{
  echo'<tr><td>'.$res['game_ID'].'</td><td>'.$res['game_Title'].'</td><td>'.$res['category_Name'].'</td></tr>';
}
echo'</table>';
function pagination($page,$num_page)
{
  echo'<ul style="list-style-type:none;">';
  for($i=1;$i<=$num_page;$i++)
  {
     if($i==$page)
{
 echo'<li style="float:left;padding:5px;">'.$i.'</li>';
}
else
{
 echo'<li style="float:left;padding:5px;"><a href="pagination.php?p='.$i.'">'.$i.'</a></li>';
}
  }
  echo'</ul>';
}
if($num_page>1)
{
 pagination($page,$num_page);
}
?> 

Now you'll get output like this:

                        Now you can paginated to next page.
