Fatal error: Call-time pass-by-reference has been removed

在使用PHP按引用传递时，可能会出现下面这样的错误：

Fatal error: Call-time pass-by-reference has been removed in 

如果有:

call_user_func($func, &$this, &$client ...

修改为

call_user_func($func, $this, $client ...

假如你的方法确实需要引用$client的值的时候，你可以在定义方法的参数使用引用，如: function($param) 改为 function(&$param)
