DebugBundle Configuration ("debug")

3.3 version

DebugBundle Configuration ("debug")

The DebugBundle allows greater integration of the VarDumper component in the Symfony full-stack framework and can be configured under the debug key in your application configuration. When using XML, you must use the http://symfony.com/schema/dic/debug namespace.

Tip

The XSD schema is available at http://symfony.com/schema/dic/debug/debug-1.0.xsd.

Configuration

max_items

type: integer default: 2500

This is the maximum number of items to dump. Setting this option to -1 disables the limit.

max_string_length

type: integer default: -1

This option configures the maximum string length before truncating the string. The default value (-1) means that strings are never truncated.

dump_destination

type: string default: null

Configures the output destination of the dumps.

By default, the dumps are shown in the toolbar. Since this is not always possible (e.g. when working on a JSON API), you can have an alternate output destination for dumps. Typically, you would set this to php://stderr:

       dump_destination: php://stderr
