function _coder_search_string($line, $rule) {
  static $php5;
  if (!isset($php5)) {
    if (function_exists('stripos')) {
      $php5 = true;
    }
    else {
      $php5 = false;
    }
  }

  // case-sensitive search with strpos() (supported everywhere)
  if (isset($rule['#case-sensitive'])) {
    return strpos($line, $rule['#value']) !== false;
  }

  // case-insensitive search with stripos() (supported in PHP 5)
  if ($php5 && !isset($rule['#case-sensitive'])) {
    return stripos($line, $rule['#value']) !== false;
  }

  // case-insensitive search
  $regex = '/' . preg_quote($rule['#value']) . '/i';
  return preg_match($regex, $line);
