Who has seen the most detailed manual on PDO Fetching?

Question

PHP

I've met before .... a lot of illustrative examples were on fetchAll, first of all. Various combinations of FETCH_COLUMN and FETCH_GROUP and cannot be found again (I generally accidentally deleted the folder in which I made a selection of such functions...

while($row=$stmt->fetch(PDO::FETCH_ASSOC)) {
       	$this->reg_data['2011'][$row['ident']]=$row;
}

How to do the same using FetchAll, provided that I do SELECT *, and although my pokazatel is unique, it goes in the fifth column ... and FETCH_UNIQUE is missing the first one ..
