PDOStatement::fetchAll --
Returns an array containing all of the result set rows
Valori restituiti
PDOStatement::fetchAll() returns an array containing
all of the remaining rows in the result set. The array represents each
row as either an array of column values or an object with properties
corresponding to each column name.
Using this method to fetch large result sets will result in a heavy
demand on system and possibly network resources. Rather than retrieving
all of the data and manipulating it in PHP, consider using the database
server to manipulate the result sets. For example, use the WHERE and
SORT BY clauses in SQL to restrict results before retrieving and
processing them with PHP.
