Public represents the global, and the inner and outer subclasses of the class can be accessed;
Copy CodeThe code is as follows:
Class test{
Public $name = ' janking ',
$sex = ' Male ',
$age = 23;
function __construct () {
echo $this->age. '

'. $this->sex. '

Private means that only this class can be used internally;
Copy CodeThe code is as follows:

}
function func () {
echo $this->age. '

Private
Protected represents a protected, only accessible in this class or subclass or parent class, and encapsulation-related magic methods:
__set (): A method that is automatically called when a private member property value is set directly
__get (): method that is called automatically when a private member property value is obtained directly
__isset (); This method is called automatically when the private property in the object is isset to see if it is stored.
__unset (); Is the method that is called automatically when you delete a private property in an object directly unset
