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!

It's no secret that Facebook has become a major traffic driver for all types of websites. Nowadays even large corporations steer consumers toward their Facebook pages instead of the corporate websites directly. And of course there are Facebook "Like" and "Recommend" widgets on every website. One...
![Conquering Impostor Syndrome]()
Two years ago I documented my struggles with Imposter Syndrome and the response was immense. I received messages of support and commiseration from new web developers, veteran engineers, and even persons of all experience levels in other professions. I've even caught myself reading the post...

Twitter does some great stuff with JavaScript. What I really appreciate about what they do is that there aren't any epic JS functionalities -- they're all simple touches. One of those simple touches is the "Login" dropdown on their homepage. I've taken...
![MooTools ASCII Art]()
I didn't realize that I truly was a nerd until I could admit to myself that ASCII art was better than the pieces Picasso, Monet, or Van Gogh could create. ASCII art is unmatched in its beauty, simplicity, and ... OK, well, I'm being ridiculous; ASCII...
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 =)
