这篇文章主要介绍了ThinkPHP进程计数类Process用法,以实例形式较为详细的分析了Process类的定义及进程计数的实现技巧,具有一定参考借鉴价值,需要的朋友可以参考

本文实例讲述了ThinkPHP进程计数类Process用法。分享给大家供大家参考。具体如下:

项目中有一个需求:由于某一后台任务比较占带宽,所以要限制进程数。花了点时间,,写了类,目前版本功能比较简单。

Process.class.php文件如下:

* @license PHP Version 3.0 {@link } */ class Process { const PROCESS_KEY = '~Process'; const PROCESS_MAXNUM = 10; /** * start * * @static * @access public * @return void */ static public function start(){ $list = self::__getList(); $name = self::__getName(); if(!isset($list[$name])){ $list[$name] = array('count'=>1, 'lasttime'=>time()); }else{ if((time()-$list[$name]['time']) > 600){ $list[$name]['count'] = 1; }else{ $list[$name]['count'] += 1; } } self::__setList($list); } /** * destory * * @static * @access public * @return void */ static public function destory(){ $list = self::__getList(); $name = self::__getName(); if(isset($list[$name])){ if($list[$name]['count'] self::getMaxnum()); } /** * getLasttime * * @static * @access public * @return void */ static public function getLasttime(){ $list = self::__getList(); $name = self::__getName(); return $list[$name]['lasttime']; } /** * clear * * @static * @access public * @return void */ static public function clear(){ F(self::PROCESS_KEY, null); } /** * __setList * * @param mixed $list * @static * @access private * @return void */ static private function __setList($list=null){ if(!is_array($list) || empty($list)) F(self::PROCESS_KEY, null); else F(self::PROCESS_KEY, $list); } /** * __getList * * @static * @access private * @return void */ static private function __getList(){ $list = F(self::PROCESS_KEY); if(!is_array($list)) return array(); else return $list; } /** * __getName * * @static * @access private * @return void */ static private function __getName(){ return (defined('GROUP_NAME') ? GROUP_NAME.'_' : '') . MODULE_NAME . '_' . ACTION_NAME; } } ?>

希望本文所述对大家基于ThinkPHP框架的php程序设计有所帮助。
