Re: [PHP] preg_match() returns false but no documentation why

Can anybody spot why this doesn't seem to be working right? The manual
( http://us2.php.net/preg_match) says it returns "false" on error, but
preg_last_error() returns 0, which I assume points to the
"PREG_NO_ERROR" error code.

<code>
preg_match("^ldap(s)?://[a-zA-Z0-9-]+\.[a-zA-Z.]{2,5}$",$this->server)
</code>

I also tried ereg(), and have searched and gone through the comments.
Why would a regex operation return false?

If you check your error log you'll find:

Warning: preg_match(): No ending delimiter '^' found in xxx.php on line xx

IMO that shouldn't be a warning, it should be an error that halts
execution so people wouldn't go looking for a non-existant
preg_last_error() when preg_match() did not even run.
