proto bool PDOStatement::closeCursor()
Closes the cursor, leaving the statement ready for re-execution.
The purpose of the function is to free up the connection to the server so that
other queries may be issued, but leaving the statement in a state that it can
be re-executed.
This is implemented either as an optional driver specific method (allowing for
maximum efficiency), or as the generic PDO fallback if no driver specific
function is installed.
The PDO generic fallback is semantically the same as writing the following code
in your PHP script:
do {
while ($stmt->fetch())
;
if (!$stmt->nextRowset())
break;
} while (true);
