Php 找不到比较数组键的方法

我有两个阵列：

Array ONE
(
    [39] => Dude, Harry [10%]
    [36] => Occonell, Tim [90%]
)

Array TWO
(
    [1] => Person, Admin
    [2] => Snow, John
    [3] => Jane, Marry
    [14] => Kelchenko, Igory
    [18] => Bery, Grass
    [36] => Occonell, Tim
)

我试图从第二个数组中删除值，若它的键等于第一个数组。因此，我的数组应该如下所示：

Array TWO
(
    [1] => Person, Admin
    [2] => Snow, John
    [3] => Jane, Marry
    [14] => Kelchenko, Igory
    [18] => Bery, Grass
)

我试图在其他地方找到答案，但找不到。

array_diff（）

方向正确，但您希望使用数组的键进行操作，因此请使用：，例如

例如：

$array2 = [
    1 => "a",
    2 => "b",
    3 => "c",
    4 => "d",
    5 => "e",
]; 

$array1 = [
    2 => "Don't want this key",
    4 => "Also don't want this one",
];

输出将是：

Array ( 
    1 => a
    3 => c
    5 => e
)

array_diff（）

例如：

$array2 = [
    1 => "a",
    2 => "b",
    3 => "c",
    4 => "d",
    5 => "e",
]; 

$array1 = [
    2 => "Don't want this key",
    4 => "Also don't want this one",
];

输出将是：

Array ( 
    1 => a
    3 => c
    5 => e
)

你可以做以下事情

foreach($arr_one as $key => $val){
    if(isset($array_2[$key]))    unset($array_2[$key]);
}

你可以做以下事情

foreach($arr_one as $key => $val){
    if(isset($array_2[$key]))    unset($array_2[$key]);
}
