  Not yet. The e modifier is used in a few spots and those areas need to be updated to use the callback instead. We will have this before the 1.0 release but until then you'll have to either use 5.4 or implement the fix. If you do the latter, let us know or better yet, put it in a pull request.

  What if you try replacing that line with something like the following:
  //e modifier is deprecated if (version_compare(PHP_VERSION, '5.5', '>=')) { $url = preg_replace_callback('#^(.*)\{(.+)\}(.*)$#', function($match) use ($fields) { if (!empty($match[2])) { return $match[1].$fields[$match[2]].$match[3]; } return ''; }, $val['url']); } else { $url = preg_replace('#^(.*)\{(.+)\}(.*)$#e', "'\\1'.((!empty(\$fields['\\2'])) ? \$fields['\\2'] : '').'\\3'", $val['url']); }

  That would have taken me a month to write, but I will try that and report back. Thanks brother :-)

  Wow, that worked:-) Thanks again admin. I've pasted the code for this particular function below in its entirety.
  
  protected function _render_actions($actions, $fields)
  {
  $str = '';
  $actions = array();
  foreach($this->_actions as $key => $val)
  {
  // normalize the data
  if (!is_array($val))
  {
  $val = array('url' => $val);
  }
  if (!empty($val['func']))
  {
  $action = call_user_func($val['func'], $fields);
  if (!empty($action)) $actions[] = $action;
  }
  else
  {
  // i love regexp... key is the e modifier that evaluates the code
  //e modifier is deprecated
  if (version_compare(PHP_VERSION, '5.5', '>='))
  {
  $url = preg_replace_callback('#^(.*)\{(.+)\}(.*)$#',
  function($match) use ($fields) {
  if (!empty($match[2]))
  {
  return $match[1].$fields[$match[2]].$match[3];
  }
  return '';
  }, $val['url']);
  }
  else
  {
  $url = preg_replace('#^(.*)\{(.+)\}(.*)$#e', "'\\1'.((!empty(\$fields['\\2'])) ? \$fields['\\2'] : '').'\\3'", $val['url']);
  }
  $attrs = (!empty($val['attrs'])) ? ' '.$this->_render_attrs($val['attrs']) : '';
  $actions[] =''.$key.'';
  }
  
  }
  if (!empty($actions)) $str = implode('  '.$this->action_delimiter.'  ', $actions);
  return $str;
  }
  
  }

  Also, this change has been pushed into the 1.0 branch.

  So what would be this same fix for
  
  Filename: libraries/fuel_page.php
  Line Number: 646
  
  The code is:
  
  $output = preg_replace('/(<body[^>]*>)/e', '"\\1\n".\$head_markers', $output);

  In the newest version of FUEL, look at the Fuel_pages::render_all_markers() method.
