104 CHAPTER 3 ■ OBJECT-ORIENTED PROGRAMMING Protected Properties and Methods When a property or method is declared protected, it can only be accessed within the class itself or in descendant classes (classes that extend the class containing the protected method). Declare the getProperty() method as protected in MyClass and try to access it directly from outside the class:
} } // Create a new object $newobj = new MyOtherClass; // Attempt to call a protected method echo $newobj->getProperty(); ?> Upon attempting to run this script, the following error shows up: The class "MyClass" was initiated! A new constructor in MyOtherClass. CHAPTER 3 ■ OBJECT-ORIENTED PROGRAMMING Fatal error: Call to protected method MyClass::getProperty() from context '' in /Applications/XAMPP/xamppfiles/htdocs/testing/test.php on line 55
