Question

Hi have this URL string which I need to extract possibly using regex but need to do it from the right side to left. For example:

http://localhost/wpmu/testsite/files/2012/06/testimage.jpg

And I need to extract this part:

2012/06/testimage.jpg

How can this be done? Thanks in advance…

UPDATE: since only the “files” in the URL is a constant, I would like to extract everything after “files”.

Answer 1

$matches = array();
$string = 'http://localhost/wpmu/testsite/files/2012/06/testimage.jpg';
preg_match('/files\/(.+)\.(jpg|gif|png)/', $string, $matches);
echo $matches[1]; // Just the '2012/06/testimage.jpg' part
