VALIDATING file types on an PHP upload script?

JdS · #1 02-Jan-2003, 07:58

I was working on an uploading process off a script I am writing and got stuck trying to validate the uploaded file type.

The script is supposed to only accept .gif, .jpg and .png files. I thought it would be simple just checking the $_FILES['file']['type'] value but was shocked to find that it's browser-dependent! So I checked 3 popular browsers: Opera, MSIE and Mozilla and so far this is what I collected:

PHP Code:


$up->SetSupportedFiles(
  array(
    'image/gif',   // Opera, Moz, MSIE
    'image/jpeg',  // Opera, Moz
    'image/png',   // Opera, Moz
    'image/pjpeg', // MSIE
    'image/x-png'  // MSIE
  )
);

Is there any other SIMPLER way to get this done without having to manually collect a list like this?
