Re: Regex pattern for preg_match_all

As far as I can tell, your problem lies in [^href]*. That will match any characters other than h, r, e or f, not anything other than the string href. Consider replacing it with [^>]*?. The ? makes it non-greedy so it will stop as soon as it can (when it matches the first href) rather than as late as it can (when it matches a >) --- Simon Welsh Sent from my phone, excuse the brevity On 19/02/2011, at 10:36, Tommy Pham <tommyhp2@gmail.com> wrote: > Hi folks, > > This is not directly relating to PHP but it's Friday so I'm gonna give > it a shot :).
