How can I sort an alphanumerical Multidimensional Array in php?

I have some json filenames in an multidimensional array, created like this: $files[] = array("name" => $file, "type" => "json") that I want to sort ascending like this:

1.File
2.File
3.File
10.File
11.File

If I order them using php sort($files) function they will be ordered like this:

1.File
10.File
11.File
2.File
3.File

If however I use natsort($files) that quote: orders alphanumeric strings in the way a human being would (php.net), I get a total mess:

3.File
2.File
10.File
1.File
11.File

Is there some better approach to order an array using php functions? Or do I have to build a custom sorting function. The server is running PHP 7.0.

You use multidimensional array, as you can see PHP have an error (Array to string conversion), you need to use usort for that task like:

$array = array(
    array("name"=>'1.File', "type" => "json"),
    array("name"=>'2.File', "type" => "json"),
    array("name"=>'3.File', "type" => "json"),
    array("name"=>'10.File', "type" => "json"),
    array("name"=>'11.File', "type" => "json"),
    );
usort($array, function($a, $b) {
    return ($a['name'] > $b['name'])
           ? 1 
           : ($a['name'] < $b['name'])
             ? -1 
             : 0;
});
print_r($array);

• usort

As @u_mulder suggest strnatcasecmp will improve the code like:

usort($array, function($a, $b) {
    return strnatcasecmp($a['name'], $b['name']);
});
