In the case of string to string comparison there must be at least one digit involved at the start of the string (or a plus/minus sign followed by digits, etc...) in order to qualify as a numeric string. if (int && string) convert to int if (string && int) convert to int if (string && string && both strings start with numerics) convert both to int There's also float versions of those, but... you get the picture. -Sara -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
