Generate Readable Byte Labels Using PHP
Whenever you manage disk space, it's infinitely easier to read when when the bytes are displayed in KB, MB, GB... format. When reading files on the disk, the server returns the disk space in bytes so it's on us programmers to program file sizes for display. Using PHP, this task is cake.
function format_bytes($bytes)
{
$labels = array('B','KB','MB','GB','TB');
for($x = 0; $bytes >= 1024 && $x < (count($labels) - 1); $bytes /= 1024, $x++);
return(round($bytes, 2).' '.$labels[$x]);
}
Users will appreciate this!

![CSS vs. JS Animation: Which is Faster?]()
How is it possible that JavaScript-based animation has secretly always been as fast — or faster — than CSS transitions? And, how is it possible that Adobe and Google consistently release media-rich mobile sites that rival the performance of native apps?

![MooTools Equal Heights Plugin: Equalizer]()
Keeping equal heights between elements within the same container can be hugely important for the sake of a pretty page. Unfortunately sometimes keeping columns the same height can't be done with CSS -- you need a little help from your JavaScript friends. Well...now you're...
![CSS Text Overlap]()
One of the important functions of CSS is to position elements.
Margin, padding, top, left, right, bottom, position, and z-index are just a few of the major players in CSS positioning.
By using the above spacing...
I always like using the right-shift operator for this kind of stuff. So instead of:
$bytes /= 1024
I would use:
$bytes >>= 10
Of course, you lost the digits after the decimal point (unless you get fancy), but on the plus side, it’s way faster than floating point division. The shift operators must be some of the loneliest operators in PHP, don’t you think?
Nice one!
I did a similar function … somewhat overkill, but a usefull thing over the years =)
