当已知数据集时，是否可以将PHP PDO与SplFixedArray一起使用？

Question

I would like to use http://uk3.php.net/manual/en/pdostatement.fetchall.php together with a query that returns a dataset of defined length.

Does PDO support fetching into http://php.net/manual/en/class.splfixedarray.php object or do I need to iterate the result set?

Answer 1

If standard array consumes too much memory, then pass a PDO statement instead, and iterate over it, using PDOStatement::fetch() . It will consume no memory at all (especially if you set PDO::MYSQL_ATTR_USE_BUFFERED_QUERY to false )
