What does it do?
The most common of the magic functions, this one is called whenever a class is created,
Why would you use it?
When you are setting up a class and need to do something as soon as the object is created. For example create a user class and set some properties on that user.
class User {
protected $firstName;
protected $lastName;
public function __construct($firstName, $lastName){
$this->firstName = $firstName;
$this->lastName = $lastName;
}
}
$user = new User('John', 'Mackenzie');These properties will now be set and accessible.
$user = new User("John", "Mackenzie");
echo $user->firstName;
