代码是：

第81行：

    {
        $text.=$e[$i]." ";
    }

配置文件行58：

session_register("views");

Answer 1

您的错误消息中只需要您所需的一切：

variable: text in /home/**/inc/function.php on line 81

这意味着以前没有设置vairalbe $text。所以先定义变量。

第二个是不再支持session_register()。所以更换它。

$_SESSION['views'] = 'test';

您之前遇到过这些错误，但您已停用通知。

Answer 2

这不是设置在if吗？

{
    $text.=$e[$i]." ";
}

如果是，并且大小写为false，则根本不会设置此变量。例如，您可以通过在脚本开头声明$text = '';来绕过此消息。这可能不是最好的做法，但它会消除信息。

未定义偏移是指 - 没有更多代码真正难以确定的 - 没有$e[3]之类的东西。它是在for循环中吗？如果是这样，可能是您使用$i <= something而不是$i < something

的问题

此外，仅使用session_register＆lt; PHP 5.4.0。

您可以这样做，例如

$_SESSION['username'] = $username;

Answer 3

在使用$text.=$e[$i]." ";之前，您必须定义$text。例如，如$text ="";或$text =[];等
