Manage Server Hard Disk Using PHP

By  on  

PHP provides some sweet functions to manage the server's hard disk. Here's how to use them.

copy()

Copies a file from a source file.

$result = copy('original.txt','new.txt');

disk_free_space()

Returns the number of bytes remaining on the disk.

$free_space = disk_free_space('/');

disk_total_space()

Returns the size of the disk in bytes.

$total_space = disk_total_space('/');

file_exists()

Confirms whether or not a file exists.

$exists = file_exists('rubbish.php');

unlink()

Deletes a file from the disk.

$file = 'rub.txt';
if(file_exists($file))
{
	unlink($file);
}
