unlink

(PHP 3, PHP 4, PHP 5)

Deletes filename. Similar to the Unix C
unlink() function. Returns TRUE on success or FALSE on failure.

Note:
As of PHP 5.0.0 unlink() can also be
used with some URL wrappers. Refer to Appendix N
for a listing of which wrappers support unlink().

Note: Context support was added
with PHP 5.0.0. For a description of contexts, refer to
Reference CLVIII, Stream Functions.

See also rmdir() for removing directories.
