Description:
------------
the test script is ok, but when I remove the annotation at line 2, the findFirst will return a bad result,
Note: the findFinst is defined in phalcon framework.

Test script:
---------------
        $parameters = [[["id=470"]]];
//        $conditions = &$parameters[0]; // the problem code
        $model = Model::findFirst($parameters);
        echo $model->name , "<br>";
        echo $this->di->get('profiler')->getLastProfile()->getSQLStatement(), "<br>";

Then why do you report the issue here?

Embarrassing for the assuming, cause I don't know it is a bug from phalcon or something wrong with the reference. The parameters pass to findFirst is considered to be the same, but actually it is not, I wonder why this happened.

There is nothing inherently wrong with creating a reference, but apparently Phalcon is doing something with $parameters that is affected by [0] being a reference. So I suggest you not do that.

As for what or why, you'd have to ask the Phalcon people. If they say there is a PHP bug then we can always revisit this.

OKļ¼Œthanks, I have ask. 
Additionally, even I do `unset($conditions)` after reference it to [0] (line 2) the result is also being bad.
