### Simple Class for Beginner!

```php
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 
  } 

  private function getName() { // getName is getter function that returns the value of instance variable $name 
    return $this->name;
  }

  public function say_my_name() {
    $name = $this->getName();
    return $name;
  }

}
$breaking_bad = 'Heisenberg';
$lab = new Lab(); // keyword new creates instance of Lab class, variable $lab points to that instance
$lab->setName($breaking_bad); // $lab variable that points to Lab instance calls setter function setName with $breaking_bad as parameter
echo "My Name is " . $lab->say_my_name(). "!";
```
