PHP ACCESS MODIFIER
•Properties and methods can have access modifiers which control where they can be accessed.
There are three access modifiers :
•Public - the property or method can be accessed from everywhere.
•Protected - the property or method can be accessed within the class and by classes derived from that class
•Private - the property or method can ONLY be accessed within the class.
SYNTAX FOR ACCESS MODIFIER IN PHP :

<?php
/* Parent Class */
class ParentClass{
/*Class Members*/
public $A = 130;
public $B = 70;
public function addition(){
echo "The sum is ", $this->A + $this->B;
}
}
/* Child class */
class ChildClass extends ParentClass{
public function subtract(){
echo ", and the difference is ", $this->A - $this->B,"." ;
}
}
$Obj = new ChildClass;
$Obj->addition() ;
