PHP对象编程有关问题，Call to a member function hello() on a non-object

$insobject = new object();<br />
$insobject->objectValue = "final";<br />
<br />
$instest = new test($insobject);<br />
<br />
//$instest->test(); 这是构造函数，一般不这样调用<br />
 <br />
class test{<br />
  var $testValue = "testValueins";<br />
  function test($insobject){<br />
    print_r($insobject);<br />
    $insobject->hello();<br />
  }<br />
}<br />
 <br />
class object{<br />
  var $objectValue = "original";<br />
  function hello(){<br />
    echo $this->objectValue; //访问属性要这样<br />
  }<br />
}<br />
