Process.class.php文件如下：

调用方法：
<?php class IndexAction extends Action { // 初始化模块 public function _initialize(){ parent::_initialize(); import('@.Util.Process'); Process::start(); } function __destruct(){ Process :: destory(); } public function index(){ C('Index_index', 3); // 动态更改限制数, 默认为10 if(Process::isOvertop()) echo "超出限制"; else "未超出限制"; } } ?>
