### Examples

Example #1 ReflectionClass::isInstantiable() example

    <?phpclass C { }interface iface {    function f1();}class ifaceImpl implements iface {    function f1() {}}abstract class abstractClass {    function f1() { }    abstract function f2();}class D extends abstractClass {    function f2() { }}trait T {    function f1() {}}class privateConstructor {    private function __construct() { }}$classes = array(    "C",    "iface",    "ifaceImpl",    "abstractClass",    "D",    "T",    "privateConstructor",);foreach($classes  as $class ) {    $reflectionClass = new ReflectionClass($class);    echo "Is $class instantiable?  ";    var_dump($reflectionClass->isInstantiable()); }?>

The above example will output:

    Is C instantiable?  bool(true)
    Is iface instantiable?  bool(false)
    Is ifaceImpl instantiable?  bool(true)
    Is abstractClass instantiable?  bool(false)
    Is D instantiable?  bool(true)
    Is T instantiable?  bool(false)
    Is privateConstructor instantiable?  bool(false)
