<?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() { }
}
class privateConstructor {
private function __construct() { }
}
$classes = array(
"C",
"iface",
"ifaceImpl",
"abstractClass",
"D",
"privateConstructor",
);
foreach($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 privateConstructor instantiable? bool(false)
