阵列与数据库的差异 [英] Array Difference from Database

问题描述

在 $ imeiserial 中，我在 $ imeitransferserial 中具有 123,222,333 .我只想显示两个数组之间的差值，我使用此代码，但它给了我错误:数组到字符串的转换我做错了什么?还是我需要此功能进行更多转换?

In $imeiserial I have 123,222,333 in $imeitransferserial I have 123,222. I just want to show the value of the difference between those 2 array, I use this code but it give me error: Array to string conversion what did I do wrong? or I need more conversion in this function?

$imei=$row["IMEI_MX"];
$imeiserial = explode(',', $imei);
$imeitransfer=$row2["IMEI_MX"];
$imeitransferserial = explode(',', $imeitransfer);

$a1=array($imeiserial);
$a2=array($imeitransferserial);

$result= array_diff_assoc($a1,$a2);

推荐答案

该 $ a1 = array 分配是多余的.随便吧:

That $a1 = array assignment is superfluous. Just leave it:

$a1 = $imeiserial; // no need to put inside an array
$a2 = $imeitransferserial; // once exploded, they are already an array

使用 * _ assoc 风格没有意义，您的键是数字，只需使用 array_diff :

And using *_assoc flavor doesn't make sense, your keys are numeric, just use array_diff:

$result = array_diff($a1,$a2);
