How to return to the larger element in the array?

$array = [ "World", "Hello", "Hello World" ]; echo array_reduce($array, function($res, $item) { return mb_strlen($res) < mb_strlen($item) ? $item : $res; }, ");

$array = [ "World", "Hello", "Hello World" ]; $last_length = 0; $last_key = null; foreach ($array as $key => $value) { if (mb_strlen($value) > $last_length) { $last_key = $key; } } var_dump($array[$last_key]);
