Apache is a web server and by default serves static content, meaning HTML documents and any other kind of text or binary files as is. Apache是Web服务器，默认情况下会提供静态内容，即HTML文档和其他任何类型的文本或二进制文件。 The way you get it to process php content and send its output is by using an Apache PHP module to invoke the PHP processor. 获取它来处理php内容并发送其输出的方法是使用Apache PHP模块调用PHP处理器。
In order to do achieve that, make sure that: 为了做到这一点，请确保：
You have installed php and you have a php module configured for apache:
sudo apt-get install php5 libapache2-mod-php5您已经安装了php，并且已经为apache配置了php模块： sudo apt-get install php5 libapache2-mod-php5Your script has a
.phpextension, such asmyscript.php, which is one of the default extensions to be handled by the php module on Apache.您的脚本具有.php扩展名，例如myscript.php，这是Apache上php模块要处理的默认扩展名之一。You restarted apache after installing the php module:
sudo service apache2 restart您在安装php模块后重新启动了apache： sudo service apache2 restartYou are hitting the proper page on your machine's browser, such as
http://localhost/myscript.php, and not something likefile:///var/www/html/myscript.php您正在机器浏览器中访问正确的页面，例如http://localhost/myscript.php，而不是file:///var/www/html/myscript.php
If it still doesn't work, you can also check the logs on /var/log/httpd/error_log to see what went wrong. 如果仍然无法解决问题，您还可以检查/var/log/httpd/error_log上的/var/log/httpd/error_log ，看看出了什么问题。
