1.2.247. Could Be Abstract Class¶
An abstract class is never instantiated, and has children class that are. As such, a ‘parent’ class that is never instantiated by itself, but has its own children instantiated could be marked as abstract.
That will prevent new code to try to instantiate it.
<?php
// Example code would actually be split over multiple files.
// That class could be abstract
class motherClass {}
// Those classes shouldn't be abstract
class firstChildren extends motherClass {}
class secondChildren extends motherClass {}
class thirdChildren extends motherClass {}
new firstChildren();
new secondChildren();
new thirdChildren();
//Not a single : new motherClass()
?>
