Más fácil de depurar


Más niveles de verbosidad

$ php app/console foo --verbose=1 # -v $ php app/console foo --verbose=2 # -vv $ php app/console foo --verbose=3 # -vvv


class MyCommand extends Command{ protected function execute($input, $output) { $verbosity = $output->getVerbosity();

if ($verbosity === OutputInterface::VERBOSITY_VERBOSE) { $output->writeln("Información"); }

if ($verbosity === OutputInterface::VERBOSITY_VERY_VERBOSE) { $output->writeln("Más información"); }

if ($verbosity === OutputInterface::VERBOSITY_DEBUG) { $output->writeln("Mucho más información"); }}


parámetros de configuración

$ console container:debug --parameters

$ console container:debug --parameter=kernel.debug


stack trace en texto plano


más información en router:match

$ php app/console router:match /demo/hello/fabienRoute "_demo_hello" matches

[router] Route "_demo_hello"Name _demo_helloPath /demo/hello/{name}Host ANYScheme ANYMethod ANYClass Symfony\Component\Routing\RouteDefaults _controller: Acme\DemoBundle\Controller\DemoController::helloActionRequirements NO CUSTOMOptions compiler_class: Symfony\Component\Routing\RouteCompilerPath-Regex #^/demo/hello/(?P<name>[^/]++)$#s


Componente Debug


echo $foo


Notice: Undefined variable: foo in index.php on line 1


use Symfony\Component\Debug\Debug;

Debug::$enable();

echo $foo;


PHP Fatal error: Uncaught exception 'Symfony\Component\Debug\Exception\ContextErrorException' with message 'Notice: Undefined variable: foo in index.php line 9' in index.php:9

Stack trace:#0 index.php(9): Symfony\Component\Debug\ErrorHandler->handle(8, 'Undefined varia...', '/Users/loalf/Pr...', 9, Array)#1 {main} thrown in index.php on line 9
