PHP Question: Getting File Mime Type new!

Hey

I know that this isn't related to the script, but if it is possible to help me out that would be great. I am trying to get the MIME type of a file already on the server. What would be the best way to do this?

Thanks for any help you can provide.Reply

Look at the code of the class. There are several methods. One -the last one in the code below- uses the compilation MIME magic, now replaced by the fileinfo extension .
 // we try to retrieve the MIME type
$info = getimagesize($this->file_src_pathname);
$this->file_src_mime = (array_key_exists('mime', $info) ? $info['mime'] : NULL);
// if we don't have a MIME type, we attempt to retrieve it the old way
if (empty($this->file_src_mime)) {
  $mime = (array_key_exists(2, $info) ? $info[2] : NULL); // 1 = GIF, 2 = JPG, 3 = PNG
  $this->file_src_mime = ($mime==1 ? 'image/gif' : ($mime==2 ? 'image/jpeg' : ($mime==3 ? 'image/png' : NULL)));
}
// if we still don't have a MIME type, we attempt to retrieve it otherwise
  if (empty($this->file_src_mime) && function_exists('mime_content_type')) {
  $this->file_src_mime = mime_content_type($this->file_src_pathname);
}
