How do I sort a PHP array by an element nested inside?

Question

I have an array like the following:

Array
(
    [0] => Array
        (
            \'name\' => \"Friday\"
            \'weight\' => 6
        )
    [1] => Array
          


        

Answer 1

You can use usort as:

function cmp($a, $b) {
   return $a['weight'] - $b['weight'];
}

usort($arr,"cmp");
