Bytes conversion

[Excalibur82]

Is there already a functions or class that can be used to convert bytes to whatever it should be such as KB, MB, GB, etc?

I have been trying to find a conversion method to include with my mod but every one of the method's I have found don't work, either I can't seem to get them to match vB or something.

Here is one I found:

PHP Code:

function ByteSize($bytes) 
    {
    $size = $bytes / 1024;
    if($size < 1024)
        {
        $size = number_format($size, 2);
        $size .= ' KB';
        } 
    else 
        {
        if($size / 1024 < 1024) 
            {
            $size = number_format($size / 1024, 2);
            $size .= ' MB';
            } 
        else if ($size / 1024 / 1024 < 1024)  
            {
            $size = number_format($size / 1024 / 1024, 2);
            $size .= ' GB';
            } 
        }
    return $size;
    }

// Returns '19.28mb'
print ByteSize('20211982'); 


Another method I found:

PHP Code:

    function formatRawSize($bytes) {
 
        //CHECK TO MAKE SURE A NUMBER WAS SENT
        if(!empty($bytes)) {
 
            //SET TEXT TITLES TO SHOW AT EACH LEVEL
            $s = array('bytes', 'kb', 'MB', 'GB', 'TB', 'PB');
            $e = floor(log($bytes)/log(1024));
 
            //CREATE COMPLETED OUTPUT
            $output = sprintf('%.2f '.$s[$e], ($bytes/pow(1024, floor($e))));
 
            //SEND OUTPUT TO BROWSER
            return $output;
 
        }
   } 


Thanks in advance

PHP Code:

function vbmksize($bytes) {
  if ($bytes < 1000 * 1024)
    return number_format($bytes / 1024, 2) . " KB";
  if ($bytes < 1000 * 1048576)
    return number_format($bytes / 1048576, 2) . " MB";
  if ($bytes < 1000 * 1073741824)
    return number_format($bytes / 1073741824, 2) . " GB";
  return number_format($bytes / 1099511627776, 2) . " TB";
}

Ok now how do I implement that into my file?

Do I use this:

$query = $db->query_read("SELECT * FROM " . TABLE_PREFIX . "download AS download 
						  LEFT JOIN " . TABLE_PREFIX . "download_screenshots AS screenshots ON (screenshots.file_id = download.id)");
	while ($dl = $db->fetch_array($query))
		{
			$id = $dl['id'];
			$version = $dl['version'];
			$name = $dl['name'];
			$size = $dl['size'];
			$description = $dl['description'];
			$username = $dl['username'];
			$userid = $dl['userid'];
			$sid = $dl['sid'];
			$screenshot = $dl['sdata'];

$this->vbmksize($size);

			eval('$display_shots .= "' . fetch_template('bfc_download_screenshot_display') . '";');
			eval('$display_bit .= "' . fetch_template('bfc_download_bit') . '";');

		}

Notice the bold red code. Is that how it gets used? vBulletin functions are still new to me, sorry.

This should work:

PHP Code:

$whatever = vbmksize($size); 


Your functions are probably fine also. I've just been using the one I posted forever and haven't ever bothered to change it.

Worked like a charm, tyvm.

BTW, what file is vbmksize() function located in? I had to create my own file but would rather include a vb file if it already exists in one.
