LAMP堆栈的PHP不工作(Ubuntu 13.10 / Apache 2.4.6)

在我的LAMP堆栈上遇到 PHP问题： PHP脚本根本没有被解析.我在清除机器上安装Ubuntu 13.10 …而且我现在看到,只有从页面清除HTML,但是PHP标签就像文本一样

其实我有什么

UPD.1：这是我的apache2.conf：http://ge.tt/6Yd8Jj91/v/0

UPD.2：今天我呃尝试删除所有的东西,只是重新安装LAMP.结果完全一样：PHP不起作用

sudo apt-get install lamp-server^

但也有趣的是,PHPmyadmin工作正常.我只是安装它：

sudo apt-get install PHP5 PHP5-cgi PHPmyadmin

原来,那里(在PHPmyadmin)是一些设置,使它使用PHP …

; This directive determines whether or not PHP will recognize code between
; <? and ?> tags as PHP source which should be processed as such. It's been
; recommended for several years that you not use the short tag "short cut" and
; instead to use the full <?PHP and ?> tag combination. With the wide spread use
; of XML and use of these tags by other languages,the server can become easily
; confused and end up parsing the wrong code in the wrong context. But because
; this short cut has been a feature for such a long time,it's currently still
; supported for backwards compatibility,but we recommend you don't use them.
