In search of the perfect URL validation regex
To clarify, I’m looking for a decent regular expression to validate URLs that were entered as user input with. I have no interest in parsing a list of URLs from a given string of text (even though some of the regexes on this page are capable of doing that). I also don’t want to allow every possible technically valid URL — quite the opposite. See the URL Standard if you’re looking to parse URLs in the same way that browsers do.
Assume that this regex will be used for a public URL shortener written in PHP, so URLs like http://localhost/, //foo.bar/, ://foo.bar/, data:text/plain;charset=utf-8,OHAI and tel:+1234567890 shouldn’t pass (even though they’re technically valid). Also, in this case I only want to allow the HTTP, HTTPS and FTP protocols.
Also, single weird leading and/or trailing characters aren’t tested for. Just imagine you’re doing this before testing $url with the regex:
$url = trim($url, '!"#$%&\'()*+,-./@:;<=>[\\]^_`{|}~');
Note that I’ve added the S modifier to all the regexes to speed up the tests. In real-world usage, this modifier can be omitted.
Here’s a plain text list of all the URLs used in the test.
Diego Perini posted his version as a gist.
