function formatBytes($bytes, $precision = 2) 
{ 
    if  ($bytes == 0) return '0 B';
    $sizes = array('B', 'KB', 'M', 'GB', 'TB');   
    $base = log($bytes, 1024);
 
    return round(pow(1024, $base - floor($base)), $precision) . ' ' . $sizes[floor($base)];
}    
   
$c = disk_total_space("c:");
$d = disk_total_space("d:");

echo "disk c total space = ".formatBytes($c)."<br />";
echo "disk c total space = ".formatBytes($d)."<br />";

/*
