You are missing the start/end delimiters is your first problem...
Which ones? I've got the starter "^" and the closer "$", so what else
am I
missing?
Whatever character you want to use:
"|^ldap(s)?"//[a-zA-Z0-9-]*\\.[a-zA-Z.]{2,5}$|"
"%^ldap(s)?"//[a-zA-Z0-9-]*\\.[a-zA-Z.]{2,5}$%"
"#^ldap(s)?"//[a-zA-Z0-9-]*\\.[a-zA-Z.]{2,5}$#"
would a regex operation return false?
It would return false if your string doesn't match the expression.
The manual claims it will return a 0 signaling "0 matches found." And
then,
under "Return Values," it's says very quickly:
"*preg_match()* returns *FALSE* if an error occurred."
If it's not returning ANYTHING I'm assuming it's faulting, but the
calling
the error function returns 0 (kind've ironic, really...).
Use === to distinguish FALSE from 0, which are not the same.
