use the disk_free_space function

http://www.php.net/manual/en/function.disk-free-space.php

this will return it in bytes so if you want it in megabytes do this (for example)

<?php
$space = disk_free_space("C:");
$space = ($space/1024)/1024;
echo round($space,2)." Mb";
?>

A simple function i just wrote which may be useful to someone in the future:

<?php
function drivestat($drive,$graph=false) {

$total = disk_total_space($drive);
$free = disk_free_space($drive);
$used = $total - $free;

$percent = ($used/$total)*100;
$percent = round($percent,0);

$total = round(($total/1024/1024/1024),1)." Gb";
$free = round(($free/1024/1024/1024),1)." Gb";
$used = round(($used/1024/1024/1024),1)." Gb";

$output =
"<b>Drive $drive Information:</b><br>\n
Total Capacity: $total<br>\n
Used: $used - Free: $free<br>\n
";

if ($graph == true) {

$output .= '
<table style="width: 180px; border: 1px solid #000000; font-size: 12px; color: #FFFFFF;" cellspacing="0">
<tr>
<td style="width: '.$percent.'%; background-color: #0000FF; text-align: center;">'.$percent.'%</td>
<td style="width: '.(100-$percent).'%; background-color: #FF0000; text-align: center;">'.(100-$percent).'%</td>
</tr>
</table>';

}

return $output;

}

echo drivestat("C:",true);
?>
