require_once of function file in a header
<p>ive got an global <code>include/header.php</code> file like:</p>

<p>UPDATE
folder structure :</p>

<pre><code> /
   include/
            header.php
            functions.php

   content/
            show.php
</code></pre>

<p><strong>include/header.php</strong></p>

<pre><code>&lt;?php
  require_once('functions.php');
  $settings = blaa;
     ....
?&gt;
</code></pre>

<p><strong>include/functions.php</strong></p>

<pre><code>&lt;?php
    function hello()
    {
      echo "hello world";
    }
?&gt;
</code></pre>

<p>and now a content file like <code>content/show.php</code></p>

<p><strong>content/show.php</strong></p>

<pre><code>&lt;?php
  require_once('../include/header.php');

  echo "show page want to say: ";
  hello();
?&gt;
</code></pre>

<p>and now if i look in the apache error_log <code>call to undefined function in content/show.php on line...</code></p>

<p>i cannot find out why :-/</p>

<p>Greetings</p>
