Question

我有两个json字符串，当我通过curl发送请求时，我已将该字符串转换为数组。

现在我的问题是如果我的字符串被更新，我想发送另一个请求。

我使用过array_diff，但它给了我错误＆＃34;注意：数组到字符串转换＆＃34;因为它的多维度。

我的json字符串是：

{"toy":["cycle","doll"],"accessory":["tv"]}

，第二个是

{"toy":["cycle","cat","rabit"],"accessory":["tv","spekers"]}

如果不在另一个数组中，我如何区分这个和获取值。

我转换后的两个数组是这样的

Array

( ['toy'] => Array ( [0] => cycle, [1] => doll ), ['accessory'] => Array ( [0] => tv )

); Array ( ['toy'] => Array ( [0] => cycle, [1] => cat, [2] => rabit ), [accessory] => Array ( [0] => tv, [1] => spekers )

);

这是我找到的解决方案

public function arrayRecursiveDiff($aArray1, $aArray2) {
    $aReturn = array();

    foreach ($aArray1 as $mKey => $mValue) {
        if (array_key_exists($mKey, $aArray2)) {
            if (is_array($mValue)) {
                $aRecursiveDiff = arrayRecursiveDiff($mValue, $aArray2[$mKey]);
                if (count($aRecursiveDiff)) { $aReturn[$mKey] = $aRecursiveDiff; }
            } else {
                if ($mValue != $aArray2[$mKey]) {
                    $aReturn[$mKey] = $mValue;
                }
            }
        } else {
            $aReturn[$mKey] = $mValue;
        }
    }

    return $aReturn;
}

我想比较两个multidimational数组或json String
