推荐答案

您的问题是您正在使用PHP中的数组.

Your problem is that you're working with an Array in PHP.

echo $ visitRecord-> getReferallist(); //返回引荐数组.

echo $visitRecord->getReferallist(); // Returns array of referrals.

当通过回显将数组转换为字符串时(因为回显输出字符串)，则会得到文本"Array".

When you cast the array to a string by echo'ing it (because echo outputs strings) then you get the text "Array".

为了通过导线发送此消息(从javascript通过AJAX($ .post)发送)，您需要将您的引荐列表转换为字符串.一种方法是序列化.您可以使用 serialize ()函数将数组转换为可字符串化的格式". www.php.net/serialize.

In order to send this over the wire(from javascript via AJAX ($.post)) you will need to convert your referral list into a string. One method is serialization. You can convert your array into a "stringable format" using the serialize() function. www.php.net/serialize.

在AJAX请求中从PHP收到此消息后，您可以使用 unserialize ()函数将可字符串格式的"数组转换回纯数组. www.php.net/unserialize.

When this is received from PHP in the AJAX request you can convert your "stringable formatted" array back into a pure array using the unserialize() function. www.php.net/unserialize.

您的代码应更改为

$ visitRecord-> getReferallist();

到

序列化($ visitRecord-> getReferallist());

然后，当您收到它时，应从以下位置更改代码

Then when it's received you should change your code from

$ referrals = $ _POST ['referalList']; //数组的可字符串化版本

$referrals = $_POST['referalList']; // Stringable version of the array

到

$ referrals = unserialize($ _ POST ['referalList']); //纯PHP数组
