Displaying file sizes in human readable format

This post was published 9 years 7 months 1 day ago. There is a chance that some APIs or software versions discussed have changed since this article was written.

This code prints out “b” for bytes, “m” for megs, etc depending on the file size.

= 1073741824) {
		$fileweight = round($fileweight / 1073741824 * 100) / 100 . "GB";
	} elseif ($fileweight >= 1048576) {
		$fileweight = round($fileweight / 1048576 * 100) / 100 . "MG";
	} elseif ($fileweight >= 1024) {
		$fileweight = round($fileweight / 1024 * 100) / 100 . "k";
	} else {
		$fileweight = $fileweight . "b";
	}
	return $fileweight;
} // end function
