This article introduces the relevant knowledge of "what is the implementation method of php instantiated object". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

To instantiate a class into an object, you just need to use the new keyword and add a method with the same name as the class name. Indicates a new object.

It is important to note that when an instantiated object does not need to pass parameters to the object, use the class name directly after the new keyword without parentheses.

The syntax format of the instantiated object is as follows:

Variable name = new class name (parameter list)

Or

Variable name = new class name

Instantiate object

Instantiating a class into an object is easy, as long as you use the new keyword followed by a method with the same name as the class. Of course, if you don't need to pass parameters to the object when instantiating the object, you can simply use the class name after the new keyword, without the need for parentheses.

The parameters are described as follows:

Variable name: through the reference name of an object created by the class, you can access members of the object through this name

New: keyword indicating that a new object is to be created

Class name: represents the type of the new object

Parameter list: specifies that the constructor of the class is used to initialize the value of the object. If there is no defined constructor in the class, PHP will automatically create a default constructor without arguments.
