See the notes at http://www.php.net/manual/en/function.ereg.php:

Note:

As of PHP 5.3.0, the regex extension is deprecated in favor of the PCRE extension. Calling this function will issue an E_DEPRECATED notice. See the list of differences for help on converting to PCRE.

Note:

preg_match(), which uses a Perl-compatible regular expression syntax, is often a faster alternative to ereg().
