title: Apache won't parse php page
body: <p>So I've installed LAMP on an Ubuntu machine for some php development and everything is working fine except instead of parsing and displaying php pages, the browser is asking me if I want to download them. I know this is a well documented issue, and I've already been to the Ubuntu page concerning it, and gone through all the potential causes. I've installed  <code>libapache2-mod-php5</code> and upon running  <code>sudo a2enmod php5</code> I get <code>module php5 already enabled</code>. So I think I've pretty much narrowed the problem down to a php file authorizations issue.</p>
  
  <p>Now I should point out that this only happened after I modified the config file to allow a <code>UserDir</code> in my <code>/home/public_html</code>. With the default configuration in folder <code>/var/www</code> php files parsed just fine, and still do, so long as I gave myself root access or modify their permisssions. And I didn't change anything else in the config file.</p>
  
  <p>So, my question is, <em>how</em> do I check/modify the php authorization files? Where are they? What exactly do I check? I can't seem to find any good info on this.</p>
