PSR1 recommends that each class should be in its own file to aid autoloaders.
                                            

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
Having each class in a dedicated file usually plays nice with PSR autoloaders
and is therefore a well established practice. If you use other autoloaders, you
might not want to follow this rule.
