The call to functionB() has too many arguments starting with $localVarB.
                                                                                                                                                    

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
This check compares calls to functions or methods with their respective definitions.
If the call has more 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.


In this case you can add the @ignore
PhpDoc
annotation to the duplicate definition and it will be ignored.

The call to functionC() misses a required argument $a.
                                                                                                                                                    

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
This check looks for function calls that miss required arguments.

The call to the function functionC() seems unnecessary as the function has no side-effects.
