Answer 1

Have you tried the filesize() function?

Answer 2

If you just want the size or other properties of a single file, you can use stat instead of du. (There's probably built-in PHP functionality for this too.) The -c option lets you customize the output format. Here's the size in bytes.

stat -c %s myfile.txt

If you really want du (to get total size of directories), you can use cut to munge the output.

du -sh -S mydir | cut -f1

Or just capture the output to a string in PHP and strip the filename there.
