ReflectionProperty::isDefault — Checks if property is a default property

Example #1 ReflectionProperty::isDefault() example
<?php
class Foo {
public $bar;
}
$o = new Foo();
$o->bar = 42;
$o->baz = 42;
$ro = new ReflectionObject($o);
var_dump($ro->getProperty('bar')->isDefault());
var_dump($ro->getProperty('baz')->isDefault());
?>
以上例程会输出：
bool(true) bool(false)
