Makes perfect sense. This is what drives me crazy. If I use a string in PHP I don't want PHP to cut this string. Either it uses this string as it is or it gives me an error/warning/false (what ever...). But silently(!!!) using a small piece of a string is not understandable. cheers Daniel -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
