php - Is there any way to variable call a PHP operator?

Question

Is there a nicer way to write this (preferably without eval!)?

function something($value, $operator) {
  switch ($operator) {
    case '=':
      return $this->arg == $value;
    case '<':
      return $this->arg < $value;
    case '>':
      return $this->arg > $value;
// etc.
  }
}

It's basicaly $operator($this->arg, $value) except you can't do that in PHP.

只是为了完整——不要留下一个未回答的问题：在 PHP 5.6 之前没有办法做到这一点。
