PHP - Classes and Objects

Consider the following PHP code:

class ParentClass {
  protected $name = 'Parent';
}
class ChildClass extends ParentClass {
  public function getName() {
    return $this->name;
  }
}
$child = new ChildClass();
echo $child->getName();

What will be the output?

AChildClass

BError: Cannot access protected property

CParent

Dnull

Step-by-Step Solution

Solution:

Step 1: Understand protected property inheritance
Protected properties are accessible in child classes, so $this->name in ChildClass works.
Step 2: Check returned value
The property $name is set to 'Parent' in ParentClass, so getName() returns 'Parent'.
Final Answer:
Parent -> Option C
Quick Check:
Protected accessible in subclass = Parent [OK]

Quick Trick: Protected allows subclass access [OK]

Common Mistakes:

Expecting error on protected access
Confusing property values
Assuming child class overrides property
