php - この状況でテストを行う方法は？

Question

2 つarrayのがあります。

$tClasseMenu = array();
$tDroitsClassMenu = array();
for ($i = 0; $i < $data['user']['classMenus']['cnt']; $i++)
{
    $tClasseMenu[$i] = $data['user']['classMenus'][$i]['class_menu_code'];
    for ($j = 0; $j < $data['user']['droit']['cnt']; $j++)
    {
        $tDroitsClassMenu[$i][$j] = $data['user']['droit'][$j]['class_menu_code'];
    }
}

これらの配列からのデータの例は次のとおりです。

class_menu_code = 7 , droit classmenucode = 6
class_menu_code = 7 , droit classmenucode = 6
class_menu_code = 7 , droit classmenucode = 6

$tClasseMenu の値が $tDroitsClassMenu に存在するかどうかをテストする方法は?
