So there is no following at all, since for all intents and purposes the character class matches a single character (unless you use a qualifier like +, ?, or *).

[PHP] Another Regex Question (General)
This may sound like a stupid question, but... within a regular expression, are the values in brackets evaluated consecutively, or no? For example: Does [a-zA-Z0-9] (yes, I know [:alnum:] is the same) mean that there can be a number, but it has to follow a letter? Or would you just do [a-zA-Z][0-9] to do that? Elementry, my dear newbie. Hehe. Thanks all! Martin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
