Thus, that is the reason why i suggest a new preg_extract function that would handle the other use cases in a optimized way. -- Rafael Dohms PHP Evangelist and Community Leader http://www.rafaeldohms.com.br http://www.phpsp.org.br -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
