php - 在这种情况下如何进行测试？

Question

有两个array：

$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'];
    }
}

这些数组中的数据示例如下：

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

如何测试 $tClasseMenu 中的值是否存在于 $tDroitsClassMenu 中？

Answer 1

PHP 的原生array_intersect函数会告诉您一个数组中的哪些值出现在另一个数组中：

$result = array_intersect( $tClassMenu, $tDroitsClassMenu );

如果$result为空，则您没有相交点。否则，$result将填充两个数组之间相交的所有点。
