从字符串php中分离一个值？ [关闭]

How can i get the certain value from the url using php?

$orginal=http://wwww.flickr.com/photos/username/1125323/in/photostream/lightbox/";

i want 1125323 from this url?

use following code:

<?php
    $orginal="http://wwww.flickr.com/photos/username/1125323/in/photostream/lightbox/";
    $url_data = explode("/",$orginal);
    $id = $url_data[5];
?>

use .*?(\d+) -> \1 as a regex.

$out = preg_replace('/.*?(\d+)/','$1', $url);

Tip: use Txt2re if you want to do this again.
