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

Agree with usort, I also sometimes use array_multisort (http://ca2.php.net/manual/en/function.usort.php) example 3, sorting database results. You could do something like:

 'Friday', 'weight' => 6),
  array('name' => 'Monday', 'weight' => 2),
);

$weight = array();
foreach($days as $k => $d) {
  $weight[$k] = $d['weight'];
}

print_r($days);

array_multisort($weight, SORT_ASC, $days);

print_r($days);
?>

Output:

Array
(
    [0] => Array
        (
            [name] => Friday
            [weight] => 6
        )

    [1] => Array
        (
            [name] => Monday
            [weight] => 2
        )

)
Array

            [weight] => 2
        )

    [1] => Array
        (
            [name] => Friday
            [weight] => 6
        )
