title: PHP include doesn't work into of a symbolic directory
body: <p>I have a problem that I am unable to resolve.</p>
  
  <p>I have two files: <code>conexion.php</code> and <code>query.php</code></p>
  
  <p>The <code>conexion.php</code> file creates a connection to the database in the variable <code>$link</code>. The code works fine.</p>
  
  <p>The query.php file queries the database using the connection created (<code>$link</code>).</p>
  
  <p>I use:</p>
  
  <pre><code>include('conexion.php');
  </code></pre>
  
  <p>The files are in the same directory. If I copy the conexion.php code into query.php works fine, but if I use "include" or "require" it doesn't work.</p>
  
  <p>Because I use SVN, the directory that contains my website in Apache is a "symbolic link" to a copy of SVN repository. If I copy the files to a real directory of Apache, the files work fine, but I need work with SVN.</p>
  
  <p>Now, I describe the directory Structure:</p>
  
  <p>Website in Apache: <code>/var/www/website/</code></p>
  
  <p>SVN copy: <code>/home/svn/backend</code></p>
  
  <p>Symbolic link: <code>/var/www/website/backend --&gt; /home/svn/backend</code></p>
  
  <pre><code>$&gt; ls /home/svn/backend
  conexion.php
  query.php
  
  
  http://localhost/website/backend
  </code></pre>
