How to write a PHP script that uses a LIKE clause to match data from a MySQL table?

We can use similar syntax of WHERE...LIKE clause in PHP function - mysql_query(). This function is used to execute a SQL command and later another PHP function – if the WHERE...LIKE clause is used with the SELECT command, mysql_fetch_array() can be used to fetch all selected data .

But if the WHERE... LIKE clause is used with the DELETE or UPDATE command, no further calls to PHP functions are required.

To illustrate this, we have the following example -

Example

In this example we are writing a PHP script which will return a tutorial_tbl' All records in the table whose author name contains 'jay' -

<?php
   $dbhost = &#39;localhost:3036&#39;;
   $dbuser = &#39;root&#39;;
   $dbpass = &#39;rootpassword&#39;;
   $conn = mysql_connect($dbhost, $dbuser, $dbpass);
   
   if(! $conn ) {
      die(&#39;Could not connect: &#39; . mysql_error());
   }
   
   $sql = &#39;SELECT tutorial_id, tutorial_title,
      tutorial_author, submission_date
      FROM tutorials_tbl
      WHERE tutorial_author LIKE "%jay%"&#39;;
     
   mysql_select_db(&#39;TUTORIALS&#39;);
   $retval = mysql_query( $sql, $conn );

   if(! $retval ) {
      die(&#39;Could not get data: &#39; . mysql_error());
   }
   
   while($row = mysql_fetch_array($retval, MYSQL_ASSOC)) {
      echo "Tutorial ID :{$row[&#39;tutorial_id&#39;]} <br> ".
         "Title: {$row[&#39;tutorial_title&#39;]} <br> ".
         "Author: {$row[&#39;tutorial_author&#39;]} <br> ".
         "Submission Date : {$row[&#39;submission_date&#39;]} <br> ".
         "--------------------------------<br>";
   }
   echo "Fetched data successfully</p><p>";
   mysql_close($conn);
?>
