从PHP数组中删除特定的键值对 [英] Remove Specific key value pair from PHP array

问题描述

我有两个键值对数组，一个是原始的，另一个是需要删除的键值对数组。我需要删除特定的组合，即$ removeArray将包含：

I have two key value pair arrays, one is the original, the other an array of key value pairs that need to be removed. I need to remove a specific combination, ie $removeArray would contain:

Array([Word] => 78)

我尝试过：

foreach($removeArray as $key => $value){unset($originalArray[$key][$value]);}

这根本不起作用。 我需要根据精确的键值对匹配项来删除。

编辑：

原始

Array ( [distribution] => 25 [watch] => 25 [electricity] => 25 [timepiece] => 8 [wristwatch] => 25 [energy] => 8 [transmission] => 8 [clock] => 16 ) 

删除

Array ( [timepiece] => 8 [energy] => 8 [watch] => 17 ) 

结果

Array ( [distribution] => 25 [watch] => 25 [electricity] => 25 [wristwatch] => 25  [transmission] => 8 [clock] => 16 )

注意：

---

NOTE:

[watch] => 25 不受影响，因为它不等于 [watch] => 17

[watch] => 25 is not affected, because it is not equal to [watch] => 17

推荐答案

您可以使用 array_diff_assoc（） ，它同时比较值和键：

You can use array_diff_assoc() for that, that compares both the values and the keys:

$result = array_diff_assoc($original, $to_remove);

示例代码：

$removeArray = array(
    'word'=>45,
    'number'=>112,
    'sign'=>2167
);

$originalArray = array(
    'lorem'=>2343,
    'ipsum'=>433,
    'word'=>78,
    'number'=>112,
    'sign'=>2167
);

$result = array_diff_assoc($originalArray, $removeArray);

结果：

Array
(
    [lorem] => 2343
    [ipsum] => 433
    [word] => 78
)
