Best way to sort directory array by extension

[RadGH]

I have an array with a list of files given from a directory using this directoryToArray() function here. And example array would be:

 

$Files[0] = "./files/my_zip.zip"
$files[1] = "./files/image.bmp"
$Files[2] = "./files/your_zip.zip"

 

I'm need some help sorting this by the extension. If anyone has some other suggestions I'm totally open to them, what I'm trying to do is list any selected folder with Javascript in a table listing the name, extension, size, and date modified. Simple. But I'd like it to be more user friendly for larger folders.

 

I've tried a few things. Simply sorting worked alphabetically, but thats not good enough. Splitting the array into a 2d array with the second element being the extension, and then sorting the second array would have worked but I couldn't find a sufficient way to accomplish that.

 

Also, is there a more efficient way to find the extension than using:

		$ext = explode("/", $file);
	$ext = explode(".", $ext[count($ext) - 1]);
	$ext = $ext[count($ext) - 1];

<?

$Files = array("./files/my_zip.zip",
		   "./files/image.bmp",
		   "./files/your_zip.zip");

foreach ($Files as $v) {
$Extensions[] = strrchr($v,'.');
}
asort($Extensions);
print_r($Extensions);

?>

Amazing... It's much shorter than everything I tried and works great.

 

All I need was "array_multisort($Extensions, $files);" instead of just asort() and its exacly what I needed!

 

Thanks!
