如何停止在浏览器窗口中打印PHP代码

为了学习，我试图在Vagrant上使用Puppet提供一个PHP Web服务器。然而，我得到的PHP代码转储在浏览器窗口，而不是执行。我试图寻找解决这个问题的办法，但在这里找不到。如有任何帮助，我将不胜感激。

这是我到目前为止所做的。

傀儡师/表现/site.pp

node /^puppet/ {
  include puppetmaster         
}   
node /^web/ {
  include webserver
  include php
}   

傀儡师/模块/网络服务器/表现/init。pp(自定义模块)

class webserver {
  notify{"provision a web server": }
  package{['git', 'links']:
    ensure => installed,
  }
  include apache        
  file{'/var/www/test':
    ensure => directory,
    owner  => 'www-data',
    group  => 'www-data',
  }
  vcsrepo { "/var/www/test":
    ensure   => present,       
    provider => git,
    source   => 'https://github.com/example/test.git',
    require => File['/var/www/test'],
  }     
  apache::vhost{'git.example.com':
    port    => '80',
    docroot => '/var/www/test',
    require => File['/var/www/test'],
  }
  host{'git.example.com':
    ip => '127.0.0.1',
  }
}

Vagrantfile

VAGRANTFILE_API_VERSION = "2"  
# Assinging static IP
$puppet_ip = "10.1.1.33"       
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
    config.vm.box = "puppetlabs/ubuntu-14.04-32-puppet"
config.vm.network "private_network", ip: "10.1.1.34"
    config.vm.define "web01" do |web|
        web.vm.hostname = "web01"       
        web.vm.network :forwarded_port, host: 1234, guest: 8983
        web.vm.network :forwarded_port, host: 11000, guest: 80
        web.vm.provision "shell", inline: "apt-get update"
        web.vm.provision "shell", inline: "echo '#{$puppet_ip} puppet' >> /etc/hosts"
    end 
end
