奇怪ing,这段代码在discuz的空间上不能运行：

[PHP] <?php
class installController
{
var $model;
var $view;

function installController($config,&$getVar=null,&$postVar=null)
{
$this->model=&new installModel($config,$getVar,$postVar);
}
}
//安装第一步
class installController_step1 extends installController
{
function installController_step1($config)
{
installController::installController($config);
$this->view=new installView_step1($this->model,$config);
}

function &getView()
{
return $this->view;
}
}
?>[/PHP]
function installController($config,&$getVar=null,&$postVar=null)
这句话报错。。在我机器上就没问题
