php - 比较并仅返回数组中的匹配项

Question

我正在寻找一种方法（在 PHP 中）使用两个不同的数组来获取匹配项的结果。数组是运动统计数据。一个数组包含统计数据的定义，另一个是 stat_id 和玩家的统计值。每个数组中的匹配项是 stat_id。我正在寻找仅在两个数组中匹配项的结果。

第一个数组包含统计定义。这是统计定义数组的一部分...

[stat] => Array

    )

这是玩家统计值数组。

[stat] => Array
    (
        [0] => SimpleXMLElement Object
            (
                [stat_id] => 4
                [value] => 0
            )

        [1] => SimpleXMLElement Object
            (
                [stat_id] => 5
                [value] => 0
            )

        [2] => SimpleXMLElement Object
            (
                [stat_id] => 6
                [value] => 0
            )

        [3] => SimpleXMLElement Object
            (
                [stat_id] => 9
                [value] => 0
            )

        [4] => SimpleXMLElement Object
            (
                [stat_id] => 10
                [value] => 0
            )

        [5] => SimpleXMLElement Object
            (
                [stat_id] => 12
                [value] => 0
            )

        [6] => SimpleXMLElement Object
            (
                [stat_id] => 13
                [value] => 0
            )

        [7] => SimpleXMLElement Object
            (
                [stat_id] => 15
                [value] => 0
            )

        [8] => SimpleXMLElement Object
            (
                [stat_id] => 16
                [value] => 0
            )

        [9] => SimpleXMLElement Object
            (
                [stat_id] => 18
                [value] => 0
            )

        [10] => SimpleXMLElement Object
            (
                [stat_id] => 57
                [value] => 0
            )

    )

Answer 1

我认为您正在寻找 array_intersect 函数之一：

• http://www.php.net/manual/en/function.array-intersect.php
• http://www.php.net/manual/en/function.array-intersect-assoc.php
• http://www.php.net/manual/en/function.array-intersect-key.php

这些允许您比较数组并根据匹配值、匹配键或两者查找重叠。
