|
|
|
class Lab { // class keyword is mandatory identifier for class creation, after class keyword goes the name of the class(e.g. Lab)
|
|
|
|
private $name = ''; // $name is instance variable, which means that every instantiated object has it's own copy of variable $name

public function setName($name) { // function setName is setter function that sets the value of instance variable $name

$this->name = $name; // because $name is the name of both instance variable and function parameter, we use $this keyword
