The VarDumperServiceProvider provides a mechanism that allows exploring then dumping any PHP variable.
Add the Symfony VarDumper Component as a dependency:
composer require symfony/var-dumper
Adding the VarDumper component as a Composer dependency gives you access to the
dump() PHP function anywhere in your code.
If you are using Twig, it also provides a
dump() Twig function and a
dump Twig tag.
The VarDumperServiceProvider is also useful when used with the Silex WebProfiler as the dumps are made available in the web debug toolbar and in the web profiler.
