implements OutputInterface

Base class for output classes.

There are five levels of verbosity:

  • normal: no option passed (normal output)
  • verbose: -v (more output)
  • very verbose: -vv (highly extended output)
  • debug: -vvv (all debug output)
  • quiet: -q (no output)

__construct()

public __construct([int $verbosity = self::VERBOSITY_NORMAL ][, bool $decorated = false ][, OutputFormatterInterface|null $formatter = null ]) : mixed
Parameters
$verbosity : int = self::VERBOSITY_NORMAL

write()

Writes a message to the output.

public write(mixed $messages[, bool $newline = false ][, int $options = self::OUTPUT_NORMAL ]) : mixed
Parameters
$messages : mixed

The message as an iterable of strings or a single string

$newline : bool = false

Whether to add a newline

$options : int = self::OUTPUT_NORMAL

A bitmask of options (one of the OUTPUT or VERBOSITY constants), 0 is considered the same as self::OUTPUT_NORMAL | self::VERBOSITY_NORMAL
