I'm not an expert on pulling in and reading files, but if all you want is
the last three characters of a file name, couldn't you just do something
like:
$extension = substr($filename, -3);
if ($extension = "pdf" || $extension = "zip") {
echo "The file is a PDF or ZIP.";
} else {
echo "Incorrect file type.";
}
??
Or maybe you are saying you want it to perform this check while the user is
attempting to upload the file and not after it has been uploaded?
