Duplicated code is one of the most pungent code smells. If you need to duplicate
the same code in three or more different places, we strongly encourage you to
look into extracting the code into a single class or operation.

The property prepaid does not exist. Did you maybe forget to declare it?
                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
In PHP it is possible to write to properties without declaring them. For example,
the following is perfectly valid PHP code:


class MyClass { }

$x = new MyClass();
$x->foo = true;





Generally, it is a good practice to explictly declare properties to avoid
accidental typos and provide IDE auto-completion:


class MyClass {
    public $foo;
}

$x = new MyClass();
$x->foo = true;
