PHP static factory method: dynamically instantiate instance of the calling class
You must create object using Late Static Binding - method get_called_class() is useful. Second option is use static keyword.
Example:
class Foo { private $name; public static function create($name) { $object = get_called_class(); return new $object($name); } private function __construct($name) { $this->name = $name; } public function getName() { return $this->name; }}class SubFoo extends Foo { public function getHelloName() { return "Hello, ". $this->getName(); }}$foo = Foo::create("Joe");echo $foo->getName(), "\n";$subFoo = SubFoo::create("Joe");echo $subFoo->getHelloName(), "\n";And output:
JoeHello, Joe
Yes, It is possible with late static binding feature of php.
Instead of
$foo = Foo::create("Joe");echo $foo->getName(), "\n"; // MUST OUTPUT: Joe$subFoo = SubFoo::create("Joe");echo $foo->getHelloName(), "\n"; // MUST OUTPUT: Hello, Joe.try this
echo parent::getName();echo self::getHelloName();
