PHP - sort hash array by key length

Question

I\'ve found a few answers to sorting by value, but not key.

What I\'d like to do is a reverse sort, so with:

    $nametocode[\'reallylongname\']=\'12         


        

Answer 1

A simple problem requires a simple solution ;-)

arsort($nametocode, SORT_NUMERIC);
$result = array_keys($nametocode);
