9. What is on Your Mind?
A byte is the smallest unit of storage which can be accessed in a computer's memory- either in RAM or ROM.It also holds exactly 8 bits.But its old view one byte was sufficient to hold one 8 bit character.Modern days especially on .NET or international versions of Win 32, 16 bits is needed.

disk_free_space
DISK_FREE_SPACE(3) 1 DISK_FREE_SPACE(3)
disk_free_space - Returns available space on filesystem or disk partition
SYNOPSIS
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
Note
This function will not work on remote files as the file to be examined must be accessible via the server's filesystem.
