Description:
------------
---
From manual page: http://www.php.net/function.fileperms
---
The first section of example 2, where it is checking for file type, is wrong.

It should be using (($perms & 0xF000) == 0xC000), (($perms & 0xF000) == 0xA000), (($perms & 0xF000) == 0x8000), etc.

Even better, why not make it a switch on ($perms & 0xF000)

Or how about just $pinfo = substr("upcudubu-ulusuuu", (($perms >> 24) & 0xF), 1);

Sorry, should have been $pinfo = substr("upcudubu-ulusuuu", (($perms >> 12) & 0xF), 1);

I don't think that the example is wrong, as the order of the
checks appear to be correct. I agree, however, that the example is
hard to read and fragile. A switch is most certainly a reasonable
improvement.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
