我正在创建一个日志文件，我想在其中一起显示旧条目和更新的条目，但是我还要强调这些条目中的更改，就像我们在编辑问题时在stackoverflow中完成的那样他们突出了编辑过的部分。
正如您所看到的，描述中存在差异，还有许多其他索引，我只是展示其中的一些。
我有两个不同的数组，如下所示：
新条目
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
)
)

我为此做了研究，发现了很多功能，我试过这个功能：
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);
但它只是向我展示了没有任何比较的新条目。希望我已经很好地解释了我的问题。
答案 0 :(得分：0)
从我收集的内容中，您正在寻找突出文本差异的方法，以查看说明之间的差异。从那里，我可以建议您将diff功能限制为b_discription，因为其他属性似乎不在您所需的范围内。您希望更改business_logo，business_name或mod_date吗？无论如何，如果可以将对象中的所有属性转换为字符串，则可以运行以下函数。
simplediff 是一个很好的脚本，可以找到两个字符串之间的区别，包括：

function diff($old, $new){
$matrix = array();
$maxlen = 0;
foreach($old as $oindex => $ovalue){
$nkeys = array_keys($new, $ovalue);
foreach($nkeys as $nindex){
$matrix[$oindex][$nindex] = isset($matrix[$oindex - 1][$nindex - 1]) ?
$matrix[$oindex - 1][$nindex - 1] + 1 : 1;
if($matrix[$oindex][$nindex] > $maxlen){
$maxlen = $matrix[$oindex][$nindex];
$omax = $oindex + 1 - $maxlen;
$nmax = $nindex + 1 - $maxlen;

}
if($maxlen == 0) return array(array('d'=>$old, 'i'=>$new));
return array_merge(
diff(array_slice($old, 0, $omax), array_slice($new, 0, $nmax)),
array_slice($new, $nmax, $maxlen),
