Wow lots of jerks in the comments here. This saved me the headache of trying to write it myself so thanks! I had an array of objects though so I had to make a slight change to where the values located:

function subval_sort($a,$subkey) {
	foreach($a as $k=>$v) {
		$b[$k] = strtolower($v->$subkey);
	}
	asort($b);
	foreach($b as $key=>$val) {
		$c[] = $a[$key];
	}
	return $c;
}

In nearly 3 years, no one – including me – has ever noticed that! Good eye!

Your function seems to have changed the Pumpkins song from “Soma” to “Cherub Rock”. Better start debugging

Great example. I’m glad there’s others out there that are willing to post examples of simple code so others can easily port it to their project. Keep up the good work.

Works very well for me. Now I can sort using different index. Thanks!

Very interesting, time saving and useful.

Thanks!

I added a few bits of the code together to allow for variables called the same name and sorting via asc or desc.

function subval_sort( $a, $subkey, $order) {
foreach( $a as $k=>$v )
$b[$k] = strtolower( $v[$subkey] );
if( $order === ‘desc’ )
arsort( $b );
else
asort( $b );
foreach( $b as $k=>$v )
$c[] = $a[$k];
return $c;
}

$albums = subval_sort($albums,’name’, ‘asc’);

Hello, first of all thank you for your wonderful post.

Secondly, I was wondering if it would be possible to take your function a little further…

I was looking to sort an array subkey by the order of another array. I have a user generated playlist, then all the songs are gathered. Then I need the gathered songs to be sorted by their trackName and match the order of the song titles the user entered in the Playlist Array.

I have made a post on Stack Overflow, regarding this possibility but I figured i’d make a post on here as well since you are indeed the original author of this wonderful function.

If you’re curious the link to the post on Stack Overflow is located here:

Otherwise, I would love to hear a response from you…

Thanks!
