Can somebody could help me please , I am php beginner student. Property Panic (2) Good job, now we have some properties. But right now $teacher and $student are the same, which should be changed immediately, correct? :-) The solution: we have to create a constructor to create different objects. This constructor is also a method, but you don't need to worry about this fact just yet. The syntax: public function __construct($prop1, $prop2) { $this->prop1 = $prop1; $this->prop2 = $prop2; } So you should remember the public keyword and the arrow notation. Some new things: You're creating a function bound to a class (a method).The constructor method has to be called __construct().Finally, the weird way to assign the values: $this->prop1 = $prop1 means that the value you pass in the __construct() function via the new keyword is assigned to $this, which represents the object you are dealing with, and ->prop1 is the actual property of the object. By creating a new instance using the new keyword, you actually call this __construct() method, which constructs the object. And that's why we have to pass in some arguments when we create an instance of a class, since this is how the properties get set! Instructions The public properties $firstname, $lastname and $age should get a value via a constructor.Change the code, so $teacher's:$firstname is "boring",$lastname is "12345",$age is 12345Add your $firstname, $lastname and $age to $student.echo the $age of $student. <?php class Person { public $isAlive = true; public $firstname; public $lastname; public $age; function __construct($firstname,$lastname,$age) { $this->firstname = $firstname; $this->lastname = $lastname; $this->age =$age; } } $object1 = new person("Tired","54321",54321); $object2 = new person("Your","name",99); echo '$isAlive->isalive', echo '$firstname->age', ?> I get this message Oops, try again! Is there still a '$teacher' variable?
