 New Comment:

can you explain why "Illuminate\Routing" should be sorted before
"Illuminate\Auth" ?

Description:
------------
Sorting with array_unique returns different results than in previous PHP versions. I suspect this is
because of https://wiki.php.net/rfc/stable_sorting

If you run the test script from below it'll return the result seeing in https://3v4l.org/9sbAq

Test script:
---------------
var_dump(array_unique([
    'Illuminate\Routing\Middleware\SubstituteBindings',
    'Illuminate\Auth\Middleware\Authorize:edit,post',
], SORT_REGULAR));

Expected result:
----------------
array(2) {
  [0]=>
  string(48) "Illuminate\Routing\Middleware\SubstituteBindings"
  [1]=>
  string(46) "Illuminate\Auth\Middleware\Authorize:edit,post"
}

Actual result:
--------------
array(2) {
  [1]=>
  string(46) "Illuminate\Auth\Middleware\Authorize:edit,post"
  [0]=>
  string(48) "Illuminate\Routing\Middleware\SubstituteBindings"
}
