fileperms() perhaps?

You'd have to compare the return value against the uid/gid the
webserver runs as, which can be obtained via getmyuid()/getmygid():

Alternatively, you could check if the file exists, then attempt to
chown/chgrp it. If the chown()/chgrp() returns false, you probably
don't have permission.
