float disk_free_space (string $directory) DESCRIPTION
Given a string containing a directory, this function will return the number of bytes available on the corresponding filesystem or disk 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. RETURN VALUES
Returns the number of available bytes as a float or FALSE on failure. EXAMPLES
Example #1 disk_free_space(3) example <?php // $df contains the number of bytes available on "/" $df = disk_free_space("/"); // On Windows: $df_c = disk_free_space("C:"); $df_d = disk_free_space("D:"); ?> NOTES
