Error Identifier: argument.byRef

Error identifiers like argument.byRef in PHPStan can be used to ignore errors locally using a comment:

// @phpstan-ignore argument.byRef
codeThatProducesTheError();

You can also use only the identifier key to ignore all errors of the same type in your configuration file in the ignoreErrors parameter:

parameters:
	ignoreErrors:
		-
			identifier: argument.byRef

You can see what identifiers are attached to reported errors by running PHPStan with -v and using the table error formatter. Here’s a list of all error identifiers.
