A prepared statement.

Some methods in that class are purposely commented out. Due to a change in how PHP defines PDOStatement, we can't define a signature for those methods that will work the same way between versions older than 5.2.6 and later versions.

Please refer to http://bugs.php.net/bug.php?id=42452 for more details.

Child implementations should either extend PDOStatement:

<?php

class DatabaseStatement_oracle extends PDOStatement implements DatabaseStatementInterface {}

?>

or implement their own class, but in that case they will also have to implement the Iterator or IteratorArray interfaces before DatabaseStatementInterface:

<?php

class DatabaseStatement_oracle implements Iterator, DatabaseStatementInterface {}

?>
