Debug Configuration Reference (DebugBundle)
Warning: You are browsing the documentation for Symfony 2.x, which is no longer maintained.
Read the updated version of this page for Symfony 7.2 (the current stable version).
The DebugBundle integrates the VarDumper component
in Symfony applications. All these options are configured under the debug
key in your application configuration.

When using XML, you must use the http://symfony.com/schema/dic/debug
namespace and the related XSD schema is available at:

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:

# app/config/config.yml
debug:
dump_destination: php://stderr
