So generally speaking, it’s best to use a generator where there is no need to rewind or iterate back over the values again in another part of the program. On the other hand, if memory is not a concern, then a simple array of the values is much faster. Understanding how PHP works “under the hood” is one of the primary defining characteristics of a PHP expert.
Essentially, it can use an object much like an associative array key to relate that object to some data or to no data at all. The first four methods in our list, __get, __set, __isset, and __unset are used for property overloading of an object. They let us define how the outside world is able to interact with properties that have a private or protected visibility, and properties that don’t even exist in our object. In the simplest terms, the $_POST superglobal is the formatted or parsed content of the body of a request made to the server with the post method.

You can change, rename, or replace the Digital class whenever you need to- all you have to do is modify the code in the ‘DigitalFactory’, instead of every instance of the class in your project. The Factory design pattern is one of the most used creational design patterns. It solves the problem of creating product objects without specifying their concrete class by maintaining a dedicated class responsible only for making objects. It is recommended to use the factory pattern when the subclass of an object instantiated can vary. Yes, the send() method is used to send values or commands to the generator.
Frequently asked questions
So if these are facilities you want or need to rely on, you may consider defining methods and properties explicitly instead. As with most things, there’s no across-the-board right answer. The pros and cons should be evaluated on a case-by-case basis. The other two methods, __call and __callStatic, perform a similar function for classes, but give us method overloading.
Take for example our array_walk usage from above which, like other functions of this type, operates in a very specific way on the subject variables which it is passed. As the function iterates over the $array, only the current value and key are passed to the anonymous function callback. There is no opportunity to pass in the $collar variable without the closure and it’s use clause . We could use the global keyword, but would needlessly pollute the global namespace with a variable that only makes sense in our very limited scope.

These patterns provide well tested, proven development/design paradigms that help to speed up the development process. Using design patterns, you can make your code more reusable, flexible, and maintainable. Objects are individual instances of the data structure defined by a class.
