Answer 1

可能不是更好的方法，但这样做可以：

$array3 = array();
foreach($array1 as $value) {
    if(in_array($value, $array2)) {
        $array3[array_search($value, $array2)] = $value;
    }
}

Answer 2

只需使用 array_intersect():

$array3 = array_intersect($array2, $array1);

I want to join 2 arrays with a standard usable
