子类继承父类 父类private问起求各位大神详解

<?php <br />
class A{<br />
	<br />
	private function test($n){<br />
		echo "11";<br />
	}<br />
}<br />
class B extends A{<br />
	function test(){<br />
		echo "22";<br />
		<br />
	}<br />
}<br />
class C extends A{<br />
<br />
}<br />
$b1=new B();<br />
$b1->test();<br />
?>
 此代码中父类有个private方法 PHP规则不是子类不能继承父类的private方法吗 可是我在子类内写了同名的方法 当其中一个有参数时就报错 如果两个都没有就没问题 请问为什么。。。。。
