title: PHP - Class
---
### 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 $name
2018-10-12 15:37:13 -04:00
public function setName($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
}
2018-10-12 15:37:13 -04:00
private function getName() { // getName is getter function that returns the value of instance variable $name
2018-10-12 15:37:13 -04:00
return $this->name;
}
public function sayMyName() {
2018-10-12 15:37:13 -04:00
$name = $this->getName();
return $name;
}
}
$breakingBad = 'Heisenberg';
$lab = new Lab();
$lab->setName($breakingBad);
echo "My Name is " . $lab->sayMyName(). "!";

```
**Note**:
The keywords *private* and *public* define the visibility of the property or the method.
- Class members declared public can be accessed everywhere.
- Members declared as private may only be accessed by the class that defines the member.
