Using usort in php with a class private function

Question

ok using usort with a function is not so complicated

This is what i had before in my linear code

function merchantSort($a,$b){
    return ....// stuf         


        

Answer 1

In this example I am sorting by a field inside the array called AverageVote.

You could include the method inside the call, which means you no longer have the class scope problem, like this...

        usort($firstArray, function ($a, $b) {
           if ($a['AverageVote'] == $b['AverageVote']) {
               return 0;
           }

           return ($a['AverageVote'] < $b['AverageVote']) ? -1 : 1;
        });
