[UPHPU] Help me speed this up. Possibly a regex question?

You could at least use a simple array and a for loop.  And putting that 
in a function makes it even easier to read.

function find_files($Month) {
	$files = array( "J-$Month-rs.pdf", "J-$Month-rp.pdf", ....);
	foreach ($files as $file) {
		if (file_exists($file)) return $file;
	}
}
$infile = find_files($Month);
