Regex - Extract TwitterUsername from URL

I'm looking for an universal regular expression which extracts the twitter username from an url.

Sample URLS

http://www.twitter.com/#!/donttrythis

http://twitter.com/KimKardashian

http://www.twitter.com/#!/KourtneyKardash/following

http://twitter.com/#!/jasonterry31/lists/memberships

this regex works fine in jQuery 

$('#inputTwitter').blur(function() {
      var twitterUserName = $(this).val();
      $(this).val(twitterUserName.match(/https?:\/\/(www\.)?twitter\.com\/(#!\/)?@?([^\/]*)/)[3])

});

I found Lombo's answer to work the best except it would not work if the URL was www.twitter.com/example . The following works for me on www as well.

  $dirty_twitter = array( 'https://twitter.com/', 'http://twitter.com/', 'www.twitter.com/', 'https://www.twitter.com/', 'http://www.twitter.com/', 'twitter.com/' );
  $clean_twitter = str_replace( $dirty_twitter, '', $clean_twitter );

This one is based on Lombo's answer, works without http(s) too, is less hungry (not keeping spaces after the username) and returns first in the result.

Check it in action: https://regex101.com/r/xI2vF3/3

For js:

(?:https?:\/\/)?(?:www\.)?twitter\.com\/(?:#!\/)?@?([^\/\?\s]*)

Lombo's answer is my favorite, but it will glom any query string in with the result:

http://www.twitter.com/#!/donttrythis?source=internet

will result in a username of "donttrythis?source=internet"

I'd modify it to be:

preg_match("|https?://(www\.)?twitter\.com/(#!/)?@?([^/\?]*)|", $twitterUrl, $matches);

Adding \? to the excluded character class after the username ensures the query string is excluded.

There are a couple more test cases to make a universal regexp.

  • https URLs are also valid
  • URLs like twitter.com/@username also go to username's profile

This should do the trick in PHP

preg_match("|https?://(www\.)?twitter\.com/(#!/)?@?([^/]*)|", $twitterUrl, $matches);

If preg_match returns 1 (a match) then the result is on $matches[3]

Try this:

^https?://(www\.)?twitter\.com/(#!/)?(?<name>[^/]+)(/\w+)*$

The sub group "name" will contain the twitter username.
This regex assumes that each URL is on its own line.

To use it in JS, use this:

^https?://(www\.)?twitter\.com/(#!/)?([^/]+)(/\w+)*$

The result is in the sub group $3.

This regex matches all four given URLs. The user name is present in $1

m[twitter\.com/+(?:#!/+)?(\w+)]

Use this to check

perl -le '$_="<url>"; m[twitter\.com/+(?:#!/+)?(\w+)]; print $1'

This one works for me (in PHP): /twitter\.com(?:\/\#!)?\/(\w+)/i
