Sorting filenames in array by type then alphabeticallyI have some php

[3dron]

I have some working PHP code that reads a directories filenames into an array. It then sorts the names alphabetically.

But now I want to sort these further by extension as well. May round-about way is to read the files in to separate arrays filtering extensions. Then sort each array independently. And finally appending all the arrays together into one array.

The downsides are numerous with my method.

Is there a way to sort by both in one array?

There may be a better way, but if you do sort the filename and the extension into two different arrays, use the multisort to sort them so that the name and ext stay matched.

ie
$filename = array(filenames entered);
$extenstions = array(extenstions entered);

array_multisort($extenstions, SORT_ASC, SORT_REGULAR, $filename, SORT_ASC, SORT_REGULAR);

then use a foreach or for loop to extract the filname and extenstion together

echo'
<ul>
';
for($i=0, $i < count($filename); $i++){
echo'
<li>' . $filename['' . $i . ''] . '.' . $extenstion['' . $i . ''] . '</li>
';
}
</ul>
