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:
use Symfony\Component\Debug\Debug;
Debug::enable();
You can also use the tools individually:
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
