       partition.

PARAMETERS

	      o $directory
		- A directory of the filesystem or disk partition.

	      Note

		      Given a file name instead of a directory, the behaviour of the function is unspecified and may differ between operating sys-
		     tems and PHP versions.

	      // $df contains the number of bytes available on "/"

	      // On Windows:
	      $df_c = disk_free_space("C:");
	      $df_d = disk_free_space("D:");
	      ?>
