fwrite when out of storage space

I have a problem that has long plagued me:
What is the best way to check if I'm out of space?
I have a file editor application (could apply to anything though).
If the server (Apache on SunOS) is out of diskspace
$fp = fopen($file,'w');
fwrite($fp,$string,strlen($string));
fclose($fp);
creates a nice 0-byte file.. no error or anything.

Do I need to write to a test file and check it's filesize first??
There's gotta be a better way.

This is a server where the log files get out of control and that's out
of my jurisdiction.

Have you tried checking the return from fclose() in this situation? In
C, there usually will be an error return because the file buffers can't
be written. Similarly an explicit fflush() normally indicates error when
the data cannot be physically written to the device.

I'm pretty sure the return value was always non-false.
Not like a false value does any good after it's wiped the file.
