Array sort in alphabetical order (Quicker Way)

Question

Hey guys i didn't found my answer in internet. Really simple question : How can i order an "complex" array in alphabetical order (the quicker way)

Exemple of an array :

array = [
    "0": [
             "username": "B_User1",
             "age": "134",
             "size": "4m13",
         ],
    "1": [
             "username": "A_User2",
             "age": "134",
             "size": "4m13",
         ],
    "2": [
             "username": "I_User3",
             "age": "134",
             "size": "4m13",
         ],
    "3": [
             "username": "R_User4",
             "age": "134",
             "size": "4m13",
         ],
    "4": [
             "username": "Z_User5",
             "age": "134",
             "size": "4m13",
         ],
    "6": [
             "username": "Q_User6",
             "age": "134",
             "size": "4m13",
         ],
];

And i want to sort this array in alphabetical order for username.

use this function with PHP 5.3

usort($myArray, function($a, $b) {
    return $a['username'] - $b['username'];
});

or use array_multisort

 $keys = array_column($myArray, 'username');
 $result = array_multisort($keys, SORT_ASC, $myArray);

And, with PHP 7 you can use the spaceship operator:

usort($myArray, function($a, $b) {
    return $a['username'] <=> $b['username'];
});

Spaceship (or strcmp if it's not available) would definitely be the way to go. Doing it with subtraction is just going to raise a lot of warnings about non-numeric values instead of sorting anything. – iainn Dec 04 '18 at 11:28
I have this ... Warning: A non-numeric value encountered – APoorDev Dec 04 '18 at 13:11
I tryied first version – APoorDev Dec 04 '18 at 13:11
Ok Solve for me (first one) : return $a->['username'] > $b->['username']; – APoorDev Dec 04 '18 at 13:16
