【请教】在Ubuntu下安装配置Apache&PHP，文件内容却直接显示出来
我按照如下方法（来自http://www.kreny.com/computer/linux/apache.html）在Ubuntu804中配置Apache和PHP都很顺利，但是启动Apache服务后，在主文件夹/var/www/中新建文件info.php 内容是，按理说应该显示关于PHP的信息表格，可是浏览器里就把文件内容显示出来了。请问这是什么问题，怎么解决？
以下安装将静态编译 php 到 apache 中去。
安装流程为：
[Configure apache 1.3.33] --> [编译安装 PHP 4.3.10] ---> [Reconfigure 编译安装 apache 1.3.33] --> [修改 httpd.conf]
这个配置将生成 libmodphp4.a 库，mod_php4.c 和一些相关的文件并且拷贝到 Apache 源程序目录中的 src/modules/php4 目录下。然后用 --activate-module=src/modules/php4/libphp4.a 编译 Apache，Apache 编译系统会生成 libphp4.a 并且将其静态地连接到 httpd 程序中。PostgreSQL 支持也直接包括在这个 httpd 程序中了，因此最终结果是单一的一个包括了所有 Apache 和 PHP 支持的 httpd 可执行文件。
--《PHP手册》--
从错误信息中总结出以上安装过程：
在配置 apache 之前如果首先配置 php 会有以下错误结果:
configure: error: Please run Apache\'s configure or src/Configure program once and try again
因此，首先要将 apache 的 source configure 一下。
安装过程：
# wget http://jp2.php.net/get/php-4.3.10.tar.gz/from/this/mirror
# wget http://sunsite.tus.ac.jp/pub/apache/httpd/apache_1.3.33.tar.gz
# tar -zxvf php-4.3.10.tar.gz
# tar -zxvf apache_1.3.33.tar.gz
# ls -l
