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);
What about file extensions that are not 3 characters in length? This
should be updated to:
<?php
$ext = substr ($filename, strrpos ($file, '.')+1);
?>
Sorry, I know this doesn't contribute to the original problem, but it
does address another... ;)
~Philip
if ($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?
