I am using a foreach loop to sort an associative array alphabetically. I would like to know if there is a more proper and/or efficient way of doing it.The array:Array(    [gr_c] => Array        (            [f] => 'value...'            [a] => 'value...'            [d] => 'value...'            [m] => 'value...'            [c] => 'value...'            [t] => 'value...'        )    [gr_a] => Array        (            [h] => 'value...'            [e] => 'value...'            [m] => 'value...'            [a] => 'value...'            [o] => 'value...'            [i] => 'value...'            [c] => 'value...'            [t] => 'value...'            [b] => 'value...'        )    [gr_b] => Array        (            [h] => 'value...'            [d] => 'value...'        ))became: Array(    [gr_c] => Array        (            [a] => 'value...'            [c] => 'value...'            [d] => 'value...'            [f] => 'value...'            [m] => 'value...'            [t] => 'value...'        )    [gr_a] => Array        (            [a] => 'value...'            [b] => 'value...'            [c] => 'value...'            [e] => 'value...'            [h] => 'value...'            [i] => 'value...'            [m] => 'value...'            [o] => 'value...'            [t] => 'value...'        )    [gr_b] => Array        (            [d] => 'value...'            [h] => 'value...'        ))used snippet:foreach ($array_name as $key => $value) {    ksort($array_name[$key]);}
Sorting an associative array alphabetically
php;array;sorting
That snippet of 3 lines you used,is fine as it is, nothing really wrong with it.It's proper, efficient, natural, easy to understand.There is just one thing I'd pick on,is that the $value variable in the foreach expression is not used.Another way to achieve the same thing without unused variables is to use & to pass the loop variable by reference:foreach ($array_name as &$arr) {    ksort($arr);}This has the advantage that the loop index variable $key is now gone too,we're working with the data that really matters, which is the $arr to sort.
