How to sort a collection of UTF-8 strings containing non-Latin chars in Laravel 5.3?

Question

Folks, I want to sort following nested collection by string alphabeticaly:

$collection = collect([
    ["name"=>"maroon"],
    ["name"=>"zoo"],
    ["name"=>"ábel"],
    ["name"=>"élof"]
])->sortBy("name");

I would expect:

1=> "ábel"
2=> "élof"
3=> "maroon"
4=> "zoo"

I got instead:

1=> "maroon"
2=> "zoo"
3=> "ábel"
4=> "élof"

I seen some PHP threads for this, but I am curious if there is any Laravel workaround for this. Thanks.

Here's a Solid way to do it:

$blank = array();
$collection = collect([
    ["name"=>"maroon"],
    ["name"=>"zoo"],
    ["name"=>"ábel"],
    ["name"=>"élof"]
])->toArray();

$count = count($collection);

for ($x=0; $x < $count; $x++) { 
    $blank[$x] = $collection[$x]['name'];
}

$collator = collator_create('en_US');
var_export($blank);
collator_sort( $collator, $blank );
var_export( $blank );

dd($blank);

Outputs:

array (
  0 => 'maroon',
  1 => 'zoo',
  2 => 'ábel',
  3 => 'élof',
)array (
  0 => 'ábel',
  1 => 'élof',
  2 => 'maroon',
  3 => 'zoo',
)

Laravel Pretty Output:

array:4 [
  0 => "ábel"
  1 => "élof"
  2 => "maroon"
  3 => "zoo"
]
