register()

static Monolog\ErrorHandler::register ( LoggerInterface  $logger,   $errorLevelMap = array(),   $exceptionLevel = null,   $fatalLevel = null  )

static

Registers a new ErrorHandler for a given Logger.

By default it will handle errors, exceptions and fatal errors

Parameters

LoggerInterface	$logger
array | false	$errorLevelMap	an array of E_* constant to LogLevel::* constant mapping, or false to disable error handling
int | false	$exceptionLevel	a LogLevel::* constant, or false to disable exception handling
int | false	$fatalLevel	a LogLevel::* constant, or false to disable fatal error handling

Returns

ErrorHandler
