PHP ereg() Function



Hello dear readers! welcome back to another section of my tutorial on PHP. In this tutorial guide, we will be discussing about the PHP ereg() Function.

The ereg() function searches for a string specified by string for a string specified by pattern, then returning true if the pattern is found, otherwise it returns false. The search is case sensitive in regard to alphabetical characters.

The optional input parameter regs contains an array of all matched expressions that were grouped by parentheses in the PHP's regular expression.


Syntax

The following is the syntax for the ereg() function -

int ereg(string pattern, string originalstring, [array regs]);

Return Value

  • It returns true if the pattern is found, otherwise false.

Example

Following is a simple example -

<?php
   $email_id = "admin@webdesigntutorialz.com";
   $retval = ereg("(\.)(com$)", $email_id);
   
   if( $retval == true )
   {
      echo "Found a .com<br>";
   } else {
      echo "Could not found a .com<br>";
   }
	
   $retval = ereg(("(\.)(com$)"), $email_id, $regs);
   
   if( $retval == true )
   {
      echo "Found a .com and reg = ". $regs[0];
   } else {
      echo "Could not found a .com";
   }
	
?>

Output
