Debug Component =============== Debug provides tools to make debugging easier. Enabling all debug tools is as easy as calling the `enable()` method on the main `Debug` class: ```php use Symfony\Component\Debug\Debug; Debug::enable(); ``` You can also use the tools individually: ```php use Symfony\Component\Debug\ErrorHandler; use Symfony\Component\Debug\ExceptionHandler; error_reporting(-1); ErrorHandler::register($errorReportingLevel); if ('cli' !== php_sapi_name()) { ExceptionHandler::register(); } elseif (!ini_get('log_errors') || ini_get('error_log')) { ini_set('display_errors', 1); } ``` Note that the `Debug::enable()` call also registers the debug class loader from the Symfony ClassLoader component when available. This component can optionally take advantage of the features of the HttpKernel and HttpFoundation components. Resources --------- You can run the unit tests with the following command: $ cd path/to/Symfony/Component/Debug/ $ composer.phar install --dev $ phpunit
