class Animal {
private $id;
public function setId($id) {
$this->id = $id;
}
}
$cat = new Animal();
$cat->setId(1);
echo $cat->getId(); // will output 1
class User {
private $id;
private $name;
public function __construct($id, $name) {
$this->id = $id;
$this->name = $name;
}
public function setId($id) {
$this->id = $id;
}
public function __toString() {

$user1 = new User(1, "John");
$user1->setId(2);
echo $user1; // will output "2 - John"
In this example, we have a more complex User class with a constructor to set the initial ID and name properties. The setId method is used to change the ID of the object. The __toString method is used to display the ID and name properties of the object in a formatted string.
The package library for the self setId method is part of the PHP core and does not require any external libraries. /**
* Create a new account object from a Twitter id
*
* @since 1.0.0
*
* @param string $id Twitter account identifier
*
* @return self|null
*/
public static function fromID($id)
{
$account = new self();
$account->setID($id);
if (!$account->hasID()) {
return;
}
return $account;
}
