Answer 1

You can do a simple str_pos() / substr() to detect if the string contains a .pdf file extension or a .html or a .png/.jpg.

Here's some example code:

if (substr($filename, -4) == '.jpg') {
       echo "Jpeg!";
}

Just make the other switches for the different file types and you're golden. Ideally, pass all the files to one function and have all the logic contained there.
