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() { }
}
$classes = array("C", "iface", "ifaceImpl", "abstractClass", "D");
foreach($classes as $class ) {
$reflectionClass = new ReflectionClass($class);
echo "Is $class instantiable? ";
var_dump($reflectionClass->IsInstantiable());
}
?>
以上例程会输出：
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)
