PHP和2多维数组基于两个键值进行比较

我有两个像这样的多维数组：

$original = Array (
[0] => Array
    (
        [time] => 1364690340
        [memberid] => 90
        [type] => single
    )

[1] => Array
    (
        [time] => 1364690341
        [memberid] => 92
        [type] => fixed
    )

[2] => Array
    (
        [time] => 1364690342
        [memberid] => 96
        [type] => single
    )
)

第二个像这样

$new = Array (
[0] => Array
    (
        [time] => 1364825750
        [memberid] => 90
        [type] => single
    )

[1] => Array
    (
        [time] => 1364825751
        [memberid] => 92
        [type] => single
    )

[2] => Array
    (
        [time] => 1364825752
        [memberid] => 96
        [type] => single
    )

[3] => Array
    (
        [time] => 1364825753
        [memberid] => 111
        [type] => single
    )
)

我的问题是：我想根据 memberid 和 type 键在 $original 数组中搜索匹配项，如果 memberid 和 type 不相同 -> 我想从 $original 数组中删除该数组。因此，在这种情况下，我想保留 [0] 数组和 [2] 数组，就像 $new 数组中一样，我具有与原始数组相同的 memberid 和相同的类型，但我想删除 [1] 数组，因为 memberid 是相同的，但是类型不同。所以我的最终 $original 数组将如下所示：

$original = Array (
[0] => Array
    (
        [time] => 1364690340
        [memberid] => 90
        [type] => single
    )

[1] => Array
    (
        [time] => 1364690342
        [memberid] => 96
        [type] => single
    )
)

好了，刚刚测试了一下，它按预期工作了。

// Presuming your two arrays are still called $new & $original
$original = array(); // your data
$new = array(); // your data

$newArray = array();
foreach($original AS $key => $val){
    $newArray[$val['memberid'] . '-' . $val['type']] = $val;
}

$original = array();
foreach($new AS $key => $val){
    if(isset($newArray[$val['memberid'] . '-' . $val['type']])){
        $original[] = $newArray[$val['memberid'] . '-' . $val['type']];
    }
}

print_r($original);
