예제

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() { }
}

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()); 
}

?>

위 예제의 출력:

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)
