Kb -> mb i php script

[meek]

I use this script to get an overview of how many files I have on my website, what type they are and what size:

<? 
$typer = array( "php", "pdf", "htm", "zip", "jpg", "avi" ); //add more types here.

foreach( $typer as $type ) { 
    $bytes=0; 
    $filer=0; 
    tree( "./", $type, 3, "" ); 
    $kb = $bytes/1024; 
    $mb=$kb/1024; 
    $gb=$mb/1024; 
    $size[$type] = $bytes; 
    $files[$type] = $filer; 
} 

$filestotal=0; 
$bytestotal=0; 
foreach( $size as $type => $bytes) { 
    echo "<b>$files[$type]</b>" . " " . "." .$type . "-files " . " " . "total size " . " " . number_format($bytes, 0, ',', '.') . " " . "bytes" . "<br />"; 
    $filestotal += $files[$type]; 
    $bytestotal += $bytes;  

} 

function tree( $path, $type ) { 
    global $bytes, $filer; 

$d = dir($path); 
while (false !== ($entry = $d->read())) { 
    $etdir = is_dir($path.$entry); 
    if(  $entry != "." && $entry != ".." && $entry != "" ) { 
        $path_parts = pathinfo($entry); 
        if( strstr($type, $path_parts["extension"]) || $type=="*" && !$etdir ) { 
            $bytes += filesize($path.$entry); 
            $filer++; 
        } 
        if( $etdir ) { 
            tree( $path.$entry."/", $type); 
        } 
    } 
} 
$d->close(); 
} 
?>  

The script shows the size of the files in bytes but I would really like to get the size in megabytes (M😎. What do I need to change in order to get that? So that eg. 120898 bytes is shown as 0.12 mb or 3202148 bytes as 3.20 mb? Anyone?
Thanks in advance.

function format_filesize($filesize)
{
	$size_array = array(
		1 => 'B',
		1024 => 'KB',
		1048576 => 'MB',
		1073741824 => 'GB'		
	);

foreach ($size_array as $key => $value)
{
	if ($filesize >= $key)
	{
		$filesize_formatted = number_format(round($filesize / $key, 2) , 2) . ' ' . $value;
	}
}

return $filesize_formatted;
}

I'm a newbie to php...where do I add this piece of code? And btw, would it be possible to get the size in mb with only two decimals? 🙂

Thanks anyway. :-)
