The trick method in PHP

The Magic method in PHP
Common methods of Magic are:

__construct (), __destruct (), __call (), __callstatic (), __get (), __set (), __isset (), __unset (), __sleep (), __wakeup (), __ ToString (), __invoke (), __set_state (), __clone () and __debuginfo ()

Some of their own understanding of magic methods:
1, the PHP object in certain operations, the specific magic method will be called. Called __construct () when constructing an object.
2, in object-oriented programming, __call () will have a relatively large use. Explanation for __call (): __call () is called when an inaccessible method is called in an object. In some frameworks, routing information and object methods, such as the CI framework, are linked by __call ().
3, about the use of __clone (): When the copy is complete, if the __clone () method is defined, then the __clone () method in the newly created object (copy generated object) is called and can be used to modify the value of the property, if necessary.
