Question

我正试图解决这个问题，但我无法解决。我找到了几个教程，但我无法修复它。

我和我的朋友正在研究相同的版本，它在他的电脑上运行没有任何问题 - 但对我而言，它不会。我们使用相同的文件，我从他那里复制了我的文件。

这里有什么问题以及为什么在我的电脑上赢得这项工作？

这是我的index.php

当我去服务器时出现此错误：

PHP notice未定义变量：tabs /var/www/private/protected/views/systemmanagement/index.php(84)

那指的是：

'tabs'       => $tabs,

为了解决这个问题，我添加了以下文件：

$tabs = array();

现在，当我执行此操作时，它可以正常运行并且不会出现任何错误，但它只会转到页面，并且不会显示任何内容。请帮助我花太多时间在这上面。

如果我把它放在我的代码中：

的print_r（$ systemInfoData）;

我明白了：

Answer 1

问题是由未定义变量$tabs引起的。

您有两个选择，正如其他贡献者正确提到的那样：

<强>予。（优选的）

在使用之前定义变量。

<强> II。（不推荐）

由于他/她的环境中设置了error_reporting级别，因此您朋友的PC上未显示错误。修改error_reporting中定义的php.ini级别。

为了隐藏php通知，请在php.ini中添加或编辑以下行

error_reporting = E_ALL & ~E_NOTICE;

或者，您可以直接从脚本设置错误报告级别，如下所示：

// Report all errors except E_NOTICE
error_reporting(E_ALL & ~E_NOTICE);

在此处阅读有关php中错误报告的更多信息：http://php.net/manual/en/function.error-reporting.php

Answer 2

您收到Undefined variable错误，因为未定义$tabs变量。

您有可以定义的多个if语句，但如果它们都评估为false，则它将保持未定义。

设置$tabs = array();定义您的变量，但它仍然没有内容。

使用PHP注意未定义的变量
