Split URL on final forward slash

Question

I'm looking for a way to split a Twitter permalink string on its final forward slash, so I can store the tweet_id. Two examples:

http://twitter.com/bloombergnews/status/55231572781170688
http://twitter.com/cnn/status/55231572781170688

Each URL has a similar format:

http://twitter.com/<screen_name>/status/<id_str>

With what regular expression would I easily capture every time?

Answer 1

This is not a job for regular expressions, IMHO.

I would do this:

$parts = explode('/', rtrim($url, '/'));
$id_str = array_pop($parts);

Answer 2

REGX ? yes; simple one liner.

$url = 'http://twitter.com/bloombergnews/status/55231572781170688';

Perl

($f1 = $url) =~ s/^.*\///;

print $f1;

---

PHP

$f1 = preg_replace("/^.*\//","",$url);

echo $f1;

EDIT: backslashes didn't show; fixed in edit box by double \\ (wierd!)
