get a specific part of a string

I have the following url. http://domain.com/userfiles/dynamic/images/whatever_dollar_1318105152.png Everything in the url can change except the userfiles part and the last underscore. Basically I want to get the part of the url which is userfiles/dynamic/images/whatever_dollar_ What is a good way to do this. I'm open or both JavaScript or php.

Assuming your string is stored in $s, simply:

echo preg_replace('/.*(userfiles.*_).*/', '$1', $s);

You could, with JavaScript, try:

var string = "http://domain.com/userfiles/dynamic/images/whatever_dollar_1318105152.png";

var newString = string.substring(string.indexOf('userfiles'),string.lastIndexOf('_'));
alert(newString); // returns: "userfiles/dynamic/images/whatever_dollar" (Without quotes).

Use parse_url in PHP to split an url in its various parts. Get the path part that is returned. It contains the path without the domain and the query string.

After that use strrpos to find the last occurrance of the _ within the path.

With substr you can copy the first part of the path (up until the found _) and you're done.
