I'm trying to match 4 backslahes using preg_match.
preg_match('/\\\\\\\\/',$subject) works fine, but preg_match('/\\{4}/',$subject) doesn't.
Perhaps I'm using {} incorrectly. Could anyone advise?
Ok I got it: Two backslashes mean you want one backslash in your string: So for the regex it looks like this: /\{4}/ Which means you want to escape the {
What you need here is:
preg_match('/\\\\{4}/', $subject);
That looks for the regex like this: /\\{4}/ and works properly.
Use this:
preg_match('/(?:\\\\){2}/',$subject, $m);
It matches 4 backslashes.
Regex is the wrong tool when you're looking for a literal string.
strpos($subject, str_repeat("\\",4)) !== false
