PHP uses one of two sets of special characters depending on whether you use single or double quotes, and leaves a single backslash preceeding a non-special character intact. PCRE removes backslashes if they're followed by non-special characters (but see /X). IOW, as opposed to PHP, PCRE will reduce \x to x for any x that's not special. Use \\x if you want \x. PHP will, however, reduce \\x to \x, since \ is special. Relying on PHP's behavior with ordinary-x \x in a PCRE introduces another grammar to the mix. -- How many Vietnam vets does it take to screw in a light bulb? You don't know, man. You don't KNOW.
