如何离线执行php任务

//设置忽略是否关闭终端窗口

ignore_user_abort(true);

ini_set('max_execution_time','0');

//采集页面函数，看不懂执行百度curl php

functiongetfiles($url,$name){

  $ch= curl_init("$url");

  $fp=fopen("$name","w");

  curl_setopt($ch, CURLOPT_FILE,$fp);

  curl_setopt($ch, CURLOPT_HEADER, 0);

  curl_exec($ch);

  curl_close($ch);

  fclose($fp);

  sleep(5);

  echo'';

}

//配置需要采集的页面路径数组

$urls=array(
