Description

float disk_free_space ( string $directory )

Given a string containing a directory, this function will return the number of bytes available on the corresponding filesystem or disk partition.

A directory of the filesystem or disk partition.

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

Return Values

Examples

Example #1 disk_free_space() example

<?php
// $df contains the number of bytes available on "/"

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

Notes

Note: This function will not work on remote files as the file to be examined must be accessible via the server's filesystem.
