With access modifiers you can set the scope of properties (variables) and properties (functions) of the class.
There are the following modifiers:
public – properties and methods can be accessed from external code and from any part of the program.
protected – properties and methods are available from the current class, as well as from descendant classes.
private – properties and methods are available only from the current class.
!If a method or property does not have an access modifier, then by default its visibility is similar to the public modifier.
<?php class Person { private $private ="private"; public $public = "public"; protected $protected = "protected"; } ?>
All properties and methods with modifiers public and protected are available to the derived class, but methods and properties with
private modifier.
In PHP, in a class, you can access variables and methods with the private and protected modifiers of an object of the same class.
