所有的PHP頁面都顯示完全空白

Question

我編寫了一個網站，不需要更多的細節，但它的工作原理，並不需要任何數據庫或類似的東西。但在我的新的Ubuntu 10.04.4 LTS服務器上，所有的PHP頁面都顯示爲空白。我已經安裝的Apache2，PHP5和一些我不知道它是用下面的命令：

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

我試圖卸載並重新安裝所有這些組件的不和運氣。沒有一個PHP頁面出現在我的瀏覽器中，它們顯示爲空白並帶有空白的源代碼，而我所有純粹的.html頁面都正常工作。

有沒有什麼辦法讓它工作，我會很樂意發佈更多的信息，但我不知道我該在哪裏得到。

PHP被配置爲不通過默認顯示錯誤。如果您檢查Apache錯誤日誌/var/log/apache2/error.log，您應該看到問題的原因。如果這是一臺開發機器，您還應該將您的php.ini文件更改爲更易於使用的設置（顯示錯誤，最大爲error_reporting）。如果它是一個生產服務器，則保留php.ini。
