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?
