int	getVerbosity() Gets the current verbosity of the output.
bool	isQuiet() Returns whether verbosity is quiet (-q).
bool	isVerbose() Returns whether verbosity is verbose (-v).
bool	isVeryVerbose() Returns whether verbosity is very verbose (-vv).
bool	isDebug() Returns whether verbosity is debug (-vvv).
	writeln(string\|array $messages, int $options = self::OUTPUT_NORMAL) Writes a message to the output and adds a newline at the end.

bool	true if the output will decorate messages, false otherwise

setVerbosity(int $level)

Sets the verbosity of the output.

Parameters

int

$level

The level of verbosity (one of the VERBOSITY constants)

int getVerbosity()

Gets the current verbosity of the output.

Return Value

int	The current level of verbosity (one of the VERBOSITY constants)

bool isQuiet()

Returns whether verbosity is quiet (-q).

Return Value

bool	true if verbosity is set to VERBOSITY_QUIET, false otherwise

bool isVerbose()

Returns whether verbosity is verbose (-v).

Return Value

bool	true if verbosity is set to VERBOSITY_VERBOSE, false otherwise

Returns whether verbosity is very verbose (-vv).

Return Value

bool	true if verbosity is set to VERBOSITYVERYVERBOSE, false otherwise

bool isDebug()

Returns whether verbosity is debug (-vvv).

Return Value

bool	true if verbosity is set to VERBOSITY_DEBUG, false otherwise

writeln(string|array $messages, int $options = self::OUTPUT_NORMAL)

Writes a message to the output and adds a newline at the end.

Parameters

string\|array	$messages	The message as an array of lines of a single string
int	$options	A bitmask of options (one of the OUTPUT or VERBOSITY constants), 0 is considered the same as self::OUTPUTNORMAL \| self::VERBOSITYNORMAL

write(string|array $messages, bool $newline = false, int $options = self::OUTPUT_NORMAL)

Writes a message to the output.

Parameters

string\|array	$messages	The message as an array of lines or a single string
bool	$newline	Whether to add a newline
int	$options	A bitmask of options (one of the OUTPUT or VERBOSITY constants), 0 is considered the same as self::OUTPUTNORMAL \| self::VERBOSITYNORMAL
