The code I'm having issues with is this:

All I want to do is grab the file extension and verify that it is
a .zip or a .pdf etc. file. This is working for small files (under
a few megs) but for some reason it fails when I get bigger. I have
increased the allowed memory size to 50 MB's I'm testing with a 44
MB file right now.
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?
I am looking to use this as a simple test prior to the upload
beginning... IE, if it's not a .zip file, don't try and upload 250MB
files :)
That code will not be executed until the file has been uploaded. Such
is the nature of the beast.
If you really need to do this your best bet is to use a client-side
uploader.
