Bug introduced by
The call to Swoole\Coroutine::writeFile() has too few arguments starting with flags. ( Ignorable by Annotation )

If this is a false-positive, you can also ignore this issue in your code via the ignore-call  annotation

116
            Coroutine::/** @scrutinizer ignore-call */ 
117
                       writeFile($filepath, $fileContent);

This check compares calls to functions or methods with their respective definitions. If the call has less arguments than are defined, it raises an issue.

If a function is defined several times with a different number of parameters, the check may pick up the wrong definition and report false positives. One codebase where this has been known to happen is Wordpress. Please note the @ignore annotation hint above.
