I think the error mechanism you are checking never even had a chance to kick in... It's kind of like an in-flight warning system for an airplane that never got off the ground... It's going to keep saying "no error" while the plane burns to a cinder if it never got turned on in the first place as it never got in the air. preg_match("/^ldap(s)?:\/\/([a-zA-Z0-9-])+\.[a-zA-Z.]{2,5}$/",$this->server) >> >> Try using | instead of / for your delimiter, so that you don't have >> to >> dink around with escaping the / in the pattern... > > > You only have to escape "/" if it's part if it's the pattern > delimiter? > > Makes the code less cluttered and more clear. > > > Fo' sho'. Yup. You only need to escape the delimiter you chose if it's in the pattern. Or, looking at it from the pattern point of view: Pick a delimiter you are unlikely to ever need in the pattern, so you won't need to escape it. -- Some people have a "gift" link here.
