比較兩個不同的多維數組並突出顯示更改

Question

我正在創建一個日志文件，該文件中我想同時顯示舊條目和更新條目，但是與此同時，我也想突出顯示新條目的更改，就像在stackoverflow中所做的那樣，當我們編輯問題時，它們突出顯示了編輯部分。

如您所見，描述有所不同，並且還有許多其他索引，我只展示其中一些。

我有兩個不同的數組，如下所示：

新條目

   Array
(
    [0] => stdClass Object
        (

            [business_logo] => 31190_photo.jpg
            [business] => Sms Factory Powered By Bds Technologies Pvt Ltd
            [b_discription] => We smsfactory are world's leading SMS messaging provider offering remarakable and reliable SMS Text and Voice messaging globally through almost all-networks of mobile phones successfully. You may contact-us anytime for making any query. Our Services are very useful economically as well as eco-friendly,
            [mod_date] => 1467736200
        )

)

舊條目

  Array
(
    [0] => stdClass Object
        (
            [business_logo] => 31190_photo.jpg
            [business] => Sms Factory Powered By Bds Technologies Pvt Ltd
            [b_discription] => We smsfactory are world's leading SMS messaging provider offering remarakable and reliable SMS Text and Voice messaging globally through almost all-networks of mobile phones successfully.

            [mod_date] => 1467736200
        )

)

我對此進行了研究，發現了很多功能，從中可以嘗試以下功能：

 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; 
} 

$arr1 = arrayRecursiveDiff($newentry,$oldentry);

但這只是向我顯示新條目，而沒有任何比較。 希望我已經很好地解釋了我的問題。

根據我的收集，您正在尋找一種突出顯示文本差異以查看描述之間差異的方法。 從那里開始，我可能建議您將diff函數限制為b_discription因為其他屬性似乎不在您需要的范圍之內。 您是否希望business_logo ， business_name或mod_date更改？ 無論如何，如果可以將以下函數轉換為字符串，則可以在對象中的所有屬性上運行它們。

simplediff是一個出色的腳本，可以發現兩個字符串之間的差異，包括：

• 存在於A中而不存在於B中（刪除）
• 存在於B中而不存在於A中（插入）
