Something that might go well with this function is the ability to list available disks. On Windows,
here's the relevant code:
<?php
/**
* Finds a list of disk drives on the server.
* @return array The array velues are the existing disks.
*/
function get_disks(){
if(php_uname('s')=='Windows NT'){
// windows
$disks=
fsutil fsinfo drives;
$disks=str_word_count($disks,1);
if($disks[0]!='Drives')return '';
unset($disks[0]);
foreach($disks as $key=>$disk)$disks[$key]=$disk.':\\';
return $disks;
}else{
// unix
$data=mount;
$data=explode(' ',$data);
$disks=array();
foreach($data as $token)if(substr($token,0,5)=='/dev/')$disks[]=$token;
return $disks;
}
}
?>
EXAMPLE OF USE:
<?php print_r(get_disks()); ?>
EXAMPLE RESULT:
Array
(
[1] => A:\
[2] => C:\
[3] => D:\
[4] => E:\
[5] => F:\
[6] => G:\
[7] => H:\
[8] => I:\
[9] => M:\
[10] => X:\
[11] => Z:\
)
Warning: This also finds empty disk drives (eg; CD or SMD drives or the more common floppy drive).
Warning2: If you want to find space usage using the info from my function, prepend the disk function
with the "@", eg:
$free=@disk_free_space('A:\\');
