Question I can't figure

[mise_me_fein]

Hi.....I'm trying the php exam trying and I think maybe I'm taking it too early now

 

Anyways...this sample question:

 

1. Which of the following methods are used to fetch data from a PDO Statement?

 

fetchColumn()

fetchObject()

fetch()

fetchClass()

fetchRow()

 

I'm just getting into PDO stuff but from what I see fetchColumn(), fetchObject() and fetch() could all be right?

 

Can someone explain to me which is right and why it is so?

Is this for real? That's a shitty exam. What value does it have being able to memorize the API? It certainly doesn't make you a good programmer.

 

Anyways, all of them are valid methods, except for fetchClass().

Given the use of language "which of the following methods are (...)" suggests the answer allows multiple answers, and would have to anyway as 4 of those can return data.

[JonnoTheDev]

<?php
class myPDO extends PDO {
   public function fetchClass() {
     // return data
   }
}
?>

 

Now they are all true! What a stupid question.

It's talking about methods in the PDOStatement class
