Easier to debug


More levels of verbosity

$ 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("Information"); }

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

if ($verbosity === OutputInterface::VERBOSITY_DEBUG) { $output->writeln("Even more information"); }}


configuration parameters

$ console container:debug --parameters

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


stack trace en plain text


more information in router:match
