所有 PHP 页面都显示完全空白

Question

我编写了一个网站，无需了解更多细节，但它可以工作，并且不需要任何数据库或类似的东西。但在我的新 Ubuntu 10.04.4 LTS 服务器上，所有 PHP 页面都显示为空白。我已经安装了 Apache2、PHP5 和一些我不知道它有什么用的东西，使用以下命令：

sudo apt-get install apache2
sudo apt-get install php5
sudo apt-get install libapache2-mod-php5
sudo /etc/init.d/apache2 restart

我尝试卸载并重新安装所有这些组件，但运气不佳。我的浏览器中没有显示任何 PHP 页面，它们显示为空白且源代码为空白，而我所有的纯 .html 页面都工作正常。

有什么办法让它工作吗？我很乐意发布更多信息，但我不知道应该从哪里获得。

Answer 1

PHP 默认配置为不显示错误。如果您检查

/var/log/apache2/error.log

处的 Apache 错误日志，您应该会看到问题的原因。如果这是一台开发机器，您还应该将

php.ini

文件更改为更适合开发人员的设置（显示错误，最大为

error_reporting

）。如果它是生产服务器，则保持 php.ini 不变。
