Question

我使用下面的代码来获取localJSON中未包含的uploadedJSON数组。

$uploadedJSON = json_decode(file_get_contents('php://input'),true);

$data = file_get_contents('results.json');
$localJSON = json_decode($data,true);   

$result = array_diff($uploadedJSON, $localJSON);

我上传的JSON如下：

Array
(
    [0] => Array
        (
            [shop] => OTCI
            [iPadNumber] => 1
            [startTime] => 03 03 14
            [endTime] => 04 04 14
            [elapsedTime] => 54
            [amount] => 15
            [receipt] => 0
            [staffID] => 123456789
        )

    [1] => Array
        (
            [shop] => OTCI
            [iPadNumber] => 1
            [startTime] => 03 03 14
            [endTime] => 04 04 14
            [elapsedTime] => 54
            [amount] => 15
            [receipt] => 1
            [staffID] => 123456789
        )

)

我的$ localJSON如下：

Array
(
    [0] => Array
        (
            [shop] => OTCI
            [iPadNumber] => 1
            [startTime] => 03 03 14
            [endTime] => 04 04 14
            [elapsedTime] => 54
            [amount] => 15
            [receipt] => 1111
            [staffID] => 123456789
        )

    [1] => Array
        (
            [shop] => OTCI
            [iPadNumber] => 1
            [startTime] => 03 03 14
            [endTime] => 04 04 14
            [elapsedTime] => 54
            [amount] => 15
            [receipt] => 2222
            [staffID] => 123456789
        )

    [2] => Array
        (
            [shop] => OTCI
            [iPadNumber] => 1
            [startTime] => 03 03 14
            [endTime] => 04 04 14
            [elapsedTime] => 54
            [amount] => 15
            [receipt] => 3333
            [staffID] => 123456789
        )

)

差别不算什么。我怎样才能获得localJSON中未包含在localJSON中的数组。

提前致谢，

Answer 1

此函数仅检查n维数组的一维。当然，您可以使用array_diff（$ array1 [0]，$ array2 [0]）;来检查更深的维度。

您很可能需要创建一个for循环，为您的二维数组调用array_dif()方法。

PHP Array_Diff没有提供任何回复
