how to sort a multidemensional array by an inner key

Question

i have this enormous array that i am pulling from an API for BattleField Bad Company 2, and the soldier stats can be pulled as a multi dimensional array with an inner array

Answer 1

You can use array_multisort for this: first provide the column you want to sort -- with array_column and as second argument the whole array. There are several options possible (see documentation), but for an ascending sort by the "rank" field, it would look like this:

array_multisort(array_column($players, "rank"), $players);

NB: For the data in the actual question here, $players would be &$arr["players"]
