Order array by how much the key is like a specific string. PHP

Question

How can I order an array of results by how much the array's keys is like a specific string. If I have a string like this:

Hello World

And an array:

array(
    [0] => "hello word"
    [1] => "herro world"
    [2] => "beho wors"

I tried using it with the Levenshtein function, but I couldn't get to understand how I could do it. I'm new to PHP.

please provide more information .. perhaps a glimpse at your failing code — lagbox, Apr 27 '14 at 16:50

Use usort() (http://us2.php.net/manual/en/function.usort.php), and have your compare function use the Levenshtein distance.

If that value is expensive to compute, then pre-compute it and store it in a separate array so that your compare function doesn't have to recompute it frequently during the sort.
