Question

* represent anything
? represent a character

like dos filename

*.test.com will match aaa.test.com but not match test.com

a dos like regexp *.test.com is similar with regexp /.*\.test\.com/ in php

is there a builtin function to test dos-like regexp in php?

Answer 1

As far as I can see in your case glob() and/or fnmatch() will do it.

$pattern = '*.test.com';
var_dump(fnmatch($pattern, 'aaa.test.com'));
var_dump(fnmatch($pattern, 'test.com'));

Note, that this are not regular expressions, because this is just a much more simple pattern matching. I don’t see a reason, why you should use regex here, thus at least fnmatch() should do it more efficient.
