572+
573+ **type **: ``string ``
574+
575+ Starting with Symfony 2.5, the Validator component introduced a new validation
576+ API. The ``api `` option is used to switch between the different implementations:
577+
578+ ``2.4 ``
579+ Use the vaidation API that is compatible with older Symfony versions.
580+
581+ ``2.5 ``
582+ Use the validation API introduced in Symfony 2.5.
583+
584+ ``2.5-bc `` or ``auto ``
585+ If you omit a value or set the ``api `` option to ``2.5-bc `` or ``auto ``,
586+ Symfony will use an API implementation that is compatible with both the
587+ legacy implementation and the ``2.5 `` implementation. You have to use
588+ PHP 5.3.9 or higher to be able to use this implementation.
