How to order a PHP array?

Question

PHP

Hello!
I can't figure out how to sort an array, by string?
I have an array like this:

array(1) {
  ["items"]=>
  array(1) {
    ["nodes:item"]=>
    array(34) {
      [0]=>
      array(2) {
        ["attribute:id"]=>
        string(5) "80857"
        ["node:value"]=>
        string(8) "Z3 (E36)"
      }
      [1]=>
      array(2) {
        ["attribute:id"]=>
        string(6) "125135"
        ["node:value"]=>
        string(7) "1 (E81)"
      }
      [2]=>
      array(2) {
        ["attribute:id"]=>
        string(6) "125024"
        ["node:value"]=>
        string(7) "1 (E87)"
      }
      [3]=>
      array(2) {
        ["attribute:id"]=>
        string(6) "125646"
        ["node:value"]=>
        string(13) "1 Coupe (E82)"
      }

Answer 1

You can use usort by passing a closure with the comparison you want.
It is not at all clear which string is being discussed from the question, but in general the task is solved in this way.

Answer 2
