Error handling

Mako converts all errors to ErrorExceptions. This allows the error handler to display an error page that contains a lot more information than the standard PHP error pages when something bad happens. The default error handler will also log the error if error logging is enabled.

Custom error handling

You can register custom error handlers for different kinds of exception types using the ErrorHandler::addHandler() method.

A great place to do so is in the app/bootstrap.php file.

$errorHandler = $container->get(ErrorHandler::class);

$errorHandler->addHandler(PDOException::class, function ($exception) {
	// Do some custom logging here
});

Your error handler should not have a return value unless you want it to stop further error handling.

$errorHandler->addHandler(Throwable::class, function ($exception) {
	// Do something else here
});

$errorHandler->addHandler(PDOException::class, function ($exception) {
	// Do some custom logging here
});

You can register multiple error handlers for any type of error. Note that the last one registered is the first one to get executed.

Disabling logging of specific exception types

Having error logging enabled can be useful even when in production, but not all error types are worth logging. You can disable error logging for specific exception types by using the error_handler.dont_log config key in your application config file.

'error_handler' =>
[
	'dont_log' =>
	[
		mako\http\exceptions\NotFoundException::class,
		mako\http\exceptions\MethodNotAllowedException::class,
	],
],

You can also disable logging programmatically using the dontLog method.

$errorHandler->dontLog(mako\http\exceptions\NotFoundException::class);

// You can also pass an array of exception types.

$errorHandler->dontLog([
	mako\http\exceptions\NotFoundException::class,
	mako\http\exceptions\MethodNotAllowedException::class,
]);
