                                    strstr

   (PHP 3, PHP 4 )
   strstr -- Find first occurrence of a string

Description

   string strstr ( string haystack, string needle)

   Returns part of haystack string from the first occurrence of needle to
   the end of haystack.

   If needle is not found, returns FALSE.

   If needle is not a string, it is converted to an integer and applied
   as the ordinal value of a character.

     Note: This function is case-sensitive. For case-insensitive
     searches, use stristr().

   Example 1. strstr() example
   <?php
   $email = 'user@example.com';
   $domain = strstr($email, '@');
   echo $domain; // prints @example.com
   ?>

     Note: If you only want to determine if a particular needle occurs
     within haystack, use the faster and less memory intensive function
     strpos() instead.

   See also ereg(), preg_match(), strchr(), stristr(), strpos(),
   strrchr(), and substr().
