public function PdoSessionHandler::createTable in Zircon Profile 8

Same name and namespace in other branches

1. 8.0 vendor/symfony/http-foundation/Session/Storage/Handler/PdoSessionHandler.php \Symfony\Component\HttpFoundation\Session\Storage\Handler\PdoSessionHandler::createTable()

Creates the table to store sessions which can be called once for setup.

Session ID is saved in a column of maximum length 128 because that is enough even for a 512 bit configured session.hash_function like Whirlpool. Session data is saved in a BLOB. One could also use a shorter inlined varbinary column if one was sure the data fits into it.

Throws

\PDOException When the table already exists

\DomainException When an unsupported PDO driver is used

File

vendor/symfony/http-foundation/Session/Storage/Handler/PdoSessionHandler.php, line 209

Class

PdoSessionHandler

Session handler using a PDO connection to read and write data.

Namespace

Symfony\Component\HttpFoundation\Session\Storage\Handler
