} elseif ($size >= 1048576) {
$fileSize = round($size / 1024 / 1024,1) . 'MB';
} elseif($size >= 1024) {
$fileSize = round($size / 1024,1) . 'KB';

... works great except: I can't manually choose in what format I need to display, say i want to show in MB only whatever the file size is. Currently if its in the GB range, it would only show in GB.
Also, how do I limit the decimal to 2?
Try something like this:
function humanFileSize($size,$unit="") {
if( (!$unit && $size >= 1<<30) || $unit == "GB")
return number_format($size/(1<<30),2)."GB";
if( (!$unit && $size >= 1<<20) || $unit == "MB")
return number_format($size/(1<<20),2)."MB";
if( (!$unit && $size >= 1<<10) || $unit == "KB")
return number_format($size/(1<<10),2)."KB";
return number_format($size)." bytes";
}
