title: included function not found - php
body: <p>I've already searched for some answers but can´t find any answer that applies to my question.</p>
  
  <pre><code>// we are in file: file.php
  include('functions.php');
  
  $i = 0;
  if($i &gt;= countServices()) break;
  [...]
  
  
  // we are in file: functions.php
  [...]
  function countServices(){
  [...]
  }
  </code></pre>
  
  <p>I have already tried to include the file <em>functions.php</em> with the absolute file path but that does not work anyway.</p>
  
  <p>The browser tells me:</p>
  
  <pre><code>"Fatal error: Call to undefined function countServices() in [...]"
  </code></pre>
  
  <p>A few days ago it worked and now...<br>
  Could you help me? </p>
