通过使用ignore_user_abort函数的特性,实现PHP计划任务,需要的朋友可以参考下。

备忘一下这个函数:
函数名称:ignore_user_abort
本函数配置或取得使用端连接中断后,香港服务器,PHP 程序是否仍继续执行。默认值为中断连接后就停止执行。在 PHP 配置文件中 (php3.ini/php.ini) 的 ignore_user_abort 选项就是配置处。本功能在 PHP 3.0.7 版之后才开始提供。
官方说明:


使用方法:

复制代码 代码如下:


ignore_user_abort(true); //即使Client断开(如关掉浏览器),PHP脚本也可以继续执行.


这样就可以实现计划任务效果了.但是还是要客户端访问程序才行.
比如说在生成静态页面、采集的时候,免备案空间,香港服务器租用,不需要在等待了。关掉浏览器吧。
例子:

复制代码 代码如下:


//test
set_time_limit(0);
ignore_user_abort(true);
$i = 0 ;
while($i ++ file_put_contents($i.'.php' , $i);
sleep(3);
}


用ignore_user_abort函数实现php计划任务

复制代码 代码如下:


ignore_user_abort(true);
set_time_limit(0);
while(1) {
  $fp = fopen('time_task.txt',"a+");
  $str = date("Y-m-d h:i:s")."\n\r";
  fwrite($fp,$str);
  fclose($fp);
  sleep(5); //半小时执行一次
}
?>
