Example #1 ReflectionClass::isInstantiable() example

<?php
class 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)
