Doh!
PREG_NO_ERROR: 0
PREG_INTERNAL_ERROR: 1
PREG_BACKTRACK_LIMIT_ERROR: 2
PREG_RECURSION_LIMIT_ERROR: 3
PREG_BAD_UTF8_ERROR: 4
So apparently, "PREG_NO_ERROR" is synonymous for "you need delimiters,
egghead."
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.

You may want \\. for the . in dot com
Ok, I tried:
preg_match("|^ldap(s)?://([a-zA-Z0-9-])+\.[a-zA-Z.]{2,5}$|",$this->server)
preg_match("|^ldap(s)?://([a-zA-Z0-9-])+\\.[a-zA-Z.]{2,5}$|",$this->server)
preg_match("|^ldap(s)?:\/\/([a-zA-Z0-9-])+\\.[a-zA-Z.]{2,5}$|",$this->server)
using: $this->server = "ldap://www.example.com";;
No luck. I'll the try tool you referred to; I have been using
regular-expressions.info for information.
Download and play with "The Regex Coach"
It does pretty color syntax highlighting of the target string and your
regex to show you what's going on, as well as a slow-motion instant
replay to "step" through it piece by piece.
Oooh, pretty colors! Stepping through sounds interesting. I'll have to check
it out.
Thanks!
