Question

If i want to get the extension of a URL with pathinfo function, i do this:

<?php
 $path_parts = pathinfo($url);
 echo $path_parts["extension"];
?>

And what’s my surprise that Apache shows the following notice:

Notice: Undefined index: extension in ...

How can i deal with it?
Thanks.

If you want to get only extension use this:

$extension = pathinfo($url, PATHINFO_EXTENSION);
echo $extension;
