本文实例讲述了php模仿asp Application对象在线人数统计实现方法。分享给大家供大家参考。具体实现方法如下:

代码如下:

/*
用法:
application('key','value'); //设置 key=value
$value = application('key'); //获取 key的值
*/
 
function application()
{
 $args = func_get_args(); //获取输入参数
 if (count($args) >2 || count($args)  $ssid = session_id(); //保存当前session_id
 session_write_close(); //结束当前session
 ob_start(); //禁止全局session发送header
 session_id("xxx"); //注册全局session_id
 session_start(); //开启全局session
 $key = $args[0];
 if (count($args) == 2) //如果有第二个参数,那么表示写入全局session
 {
  $re = ($_session[$key] = $args[1]);
 }
 else // 如果只有一个参数,那么返回该参数对应的value
 {
  $re = $_session[$key];
 }
 session_write_close(); //结束全局session
 session_id($ssid); //重新注册上面被中断的非全局session
 session_start(); //重新开启
 ob_end_clean(); //抛弃刚刚由于session_start产生的一些header输出
 return $re; 
}

希望本文所述对大家的php程序设计有所帮助。
