Re: Preg_match.

Actually, this matches nothing, at least on my computer. You need to set the minimum count in the repetition ( {0,18} ), and you can use the PCRE_CASELESS option to shorten the pattern: '/^[0-9a-z][0-9a-z._]{0,18}[0-9a-z]$/i' BTW, in PHP, PCRE regular expressions are about twice as fast as the POSIX ones.
