Preface Sometimes, I really doubt that the lesson of this principle is a waste of time over time. After operating system principle we can not implement an operating system by ourselves; we can't get a decent DBMS out of the database. After learning

For example, I have a test object, the first instance of the object, and then the object after the instantiation, this time why also find the object? $test = new Test();echo $test->run();class Test{ public function run(){ return 'run---';

Chapter 2 intermediary Mode Mediator), Uses an intermediary object to encapsulate a series of object interactions. The intermediary makes the objects do not need to be explicitly referenced to each other, so that the coupling is loose and
