Did I do this weird?

[tibberous]

I needed to soft files by their extension.

 

$dir = opendir($path);
$files = array();

function sortByExt($x, $y){
	return strcmp($x['ext'], $y['ext']);
}

while($file = readdir($dir)){
	if($file == '.' || $file == '..') continue;
	$ext = explode('.', $file);
	$ext = array_pop($ext);
	$files[] = array('file'=>$file, 'ext'=>$ext);
}

usort($files, "sortByExt");

 

I was thinking there was a way to do it without usort, just like a 'sort by value' kind of thing.

That's how I'd do it, that's what usort is for.

That's what it's used for.  You did good.
