title: PHP: Getting a blank page
body: <p>I am getting a blank page on a PHP when I use require_once to include another php. This is working, however, on other files. Now, I reduced all my code to this:</p>
  
  <pre><code>echo 'testing';
  require_once 'C:/xampp/htdocs/folder/file.php';
  echo 'now show this';
  </code></pre>
  
  <p>The code above just produces a blank page, no errors or anything, even though this file is being used on other files with no problems. I put a trace on the top of that file and nothing. I am using it in the same way the other files are using it, just a require_once.</p>
  
  <p>If I comment file.php to nothing but a line reading <code>echo ' - inside file'</code>, the line is displayed, however it is not continuing with the rest. Thus, showing the following output:</p>
  
  <pre><code>testing - inside file
  </code></pre>
  
  <p>It's not going with the rest... What could be the reason of this? </p>
