Getting an images extension from a url

[pleek]

ok, so i know how to get the images extension if its a direct path to the image. My problem is my script will be using file paths such as..

http://www.tinyportal.net/index.php?action=dlattach;attach=18707;type=avatar

 

How can i get that files extension?

Cut on the question mark and then cut on the last period.

 

$ext=array_pop(explode('.',array_shift(explode('?',$url))));

parse_url()

$ext=array_pop(explode('.',array_shift(explode('?',$url))));

Won't that show php as the filetype? The file itself is a png image.

 

parse_url()

 

I read the php manual for parse_url and im not seeing how that will get the files extension.

You won't be able to get the image's file extension from that URL simply because it's not there.

 

If the script is on your server you could somehow find the source image the same way the script does and get the file extension/type that way.

 

As a lazy/bad alternative you could use getimagesize() on the URL along with image_type_to_extension() to find the image's extension/type.
