Hello folks! welcome back to a new section of our tutorial on PHP. In this section of our PHP tutorial, we will be studying about how to create a Pagination using PHP.
It is always possible that your SQL SELECT statement query may result into thousands of records. But it is not a good idea to show all the results on a single page. So we can divide this result into many pages based on your own needs.
Paging simply means displaying your query result in many pages instead of just putting them all into a single long page.
MySQL helps to create paging using LIMIT clause which takes in two arguments. First argument as offset and second argument how many records should be returned from the database.

The following below is a simple example to fetch records using LIMIT clause to create paging.
Example
Try the following example below to display 10 records per page -
<html> <head> <title>Paging Using PHP</title> </head> <body> <?php $dbhost = 'localhost:3036'; $dbuser = 'root'; $dbpass = 'rootpassword'; $rec_limit = 10; $conn = mysql_connect($dbhost, $dbuser, $dbpass); if(! $conn ) { die('Could not connect: ' . mysql_error()); } mysql_select_db('test_db'); /* Get total number of records */ $sql = "SELECT count(emp_id) FROM employee "; $retval = mysql_query( $sql, $conn ); if(! $retval ) { die('Could not get data: ' . mysql_error()); } $row = mysql_fetch_array($retval, MYSQL_NUM ); $rec_count = $row[0]; if( isset($_GET{'page'} ) ) { $page = $_GET{'page'} + 1; $offset = $rec_limit * $page ; }else { $page = 0; $offset = 0; } $left_rec = $rec_count - ($page * $rec_limit); $sql = "SELECT emp_id, emp_name, emp_salary ". "FROM employee ". "LIMIT $offset, $rec_limit"; $retval = mysql_query( $sql, $conn ); if(! $retval ) { die('Could not get data: ' . mysql_error()); } while($row = mysql_fetch_array($retval, MYSQL_ASSOC)) { echo "EMP ID :{$row['emp_id']} <br> ". "EMP NAME : {$row['emp_name']} <br> ". EMP SALARY : {$row['emp_salary']} <br> ". "--------------------------------<br>"; } if( $page > 0 ) { $last = $page - 2; echo "<a href = \"$_PHP_SELF?page = $last\">Last 10 Records</a> |"; echo "<a href = \"$_PHP_SELF?page = $page\">Next 10 Records</a>"; }else if( $page == 0 ) { echo "<a href = \"$_PHP_SELF?page = $page\">Next 10 Records</a>"; }else if( $left_rec < $rec_limit ) { $last = $page - 2; echo "<a href = \"$_PHP_SELF?page = $last\">Last 10 Records</a>"; } mysql_close($conn); ?> </body> </html>
