我正在运行ipb并且我正在使用名为ibeconomy的插件，在用户购买并从商店获奖并使用它后，他们会收到此错误。警告：第196行非法字符串偏移'错误'/ibEconomy/sources/shop_items/award_item.php。

这是代码，我不确定究竟发生了什么。

答案 0 :(得分：0)
您将$returnMe初始化为空字符串，但您尝试将其用作关联数组。您应该将其初始化为空数组。所以改变这一行：
$returnMe = '';
为：
$returnMe = array();
答案 1 :(得分：0)
$returnMe目前是一个字符串。它不是一个数组。你应该这样做：
$returnMe = []; // or array() for php < 5.4
...
if (!is_null($returnMe['error'])){
// Here you can evaluate $returnMe['error']
}
