Working with results challenge is misleading and wrong. Here is why:

What i am talking about is "Working with results" challenge that is in PHP path > Integrating php with databases. First what is wrong about that is the statement that says "The data from the database is currently in a PDOStatement object named $results" , well that is completely not true. $results that is given in that context is not PDOStatement object, but PDO object itself. You can copy the code and var_dump it. But bottom line is that you do not call query method on PDOStatement, you do that on PDO object itself. And then what you get is PDOStatement object.

Second thing is that $results variable actually is not seen in code that is suppose to show what it is.(Though it is clearly a PDO object, because you can see $results->query(); method called on it, that is what shows that it is not PDOStatement object.)

In my opinion this challenge and this course is poorly made , because it focuses too much on OOP, before we even get to OOP. And mistake like this , i think misleads even more.

code given:

<?php
include "helper.php";

/* 
 * helper.php contains
 * $results->query("SELECT member_id, email, fullname, level FROM members");
 */
