title: Issue replacing content with str_replace
body: <p>I'm working with a CMS spanish website, and I'm trying to replace the months to spanish.</p>
  
  <p>This is how it looks like with the date function <strong>date("F j, Y, g:i a")</strong>:</p>
  
  <pre><code>August 24, 2011, 1:47 pm
  </code></pre>
  
  <p>Now I want it to look like this:</p>
  
  <pre><code>Agosto 24, 2011, 1:47 pm
  </code></pre>
  
  <p>Using an example from the <a href="http://php.net/manual/en/function.str-replace.php" rel="nofollow">Php Documentation</a> I made this:</p>
  
  <pre><code>$p['time'] = date("F j, Y, g:i a");
          $time_english = $p['time'];
          $search  = $time_english('August', 'September', 'October', 'November', 'December');
          $replace = $times_spanish('Agosto', 'Septiembre', 'Octubre', 'Noviembre', 'Diciembre');
          $subject ='August';
          str_replace($search, $replace, $subject);
  </code></pre>
  
  <p>The following error appears:</p>
  
  <pre><code>Fatal error: Call to undefined function August 24, 2011, 3:50 pm() in
      $search  = $time_english('August', 'September', 'October', 'November', 'December');
  </code></pre>
