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.

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:

YAML

debug:
   dump_destination: php://stderr

XML

<?xml version="1.0" encoding="UTF-8" ?>
<container xmlns="http://symfony.com/schema/dic/debug"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:debug="http://symfony.com/schema/dic/debug"
    xsi:schemaLocation="http://symfony.com/schema/dic/services http://symfony.com/schema/dic/services/services-1.0.xsd
        http://symfony.com/schema/dic/debug http://symfony.com/schema/dic/debug/debug-1.0.xsd">

    <debug:config dump-destination="php://stderr" />
</container>

PHP

$container->loadFromExtension('debug', array(
   'dump_destination' => 'php://stderr',
));
