Resolved Process URL parameter

[Mooseman]

I'd like to process a URL parameter, process it, and echo it. Here's an example:

URL: example.com/file.php?item=set2image4
echo: set2/image4
URL: example.com/file.php?item=image6
echo:set1/image6

set1 would be inserted by default if set2 does not exist in the parameter. How can I process that with PHP? Thank you!

Think this should work.

PHP Code:

$item = (substr($_GET['item'], 0, 3) != "set") ? "set1/".$_GET['item'] : substr($_GET['item'], 0, 4)."/".substr($_GET['item'], 5);

if (!file_exists($item)) {
   die ("Sorry, the file you are searhing for does not exist");
}
else {
   // Do something else
}
