例-1 一个的ignore_user_abort（）的例子，配合set_time_limit()函数 和一个死循环就可以实现计划任务功能。

　　<?php

　　// Ignore user aborts and allow the script

　　// to run forever

　　ignore_user_abort (true);

　　set_time_limit (0);

　　echo ‘Testing connection handling in PHP‘ ;

　　// Run a pointless loop that sometime

　　// hopefully will make us click away from

　　// page or click the "Stop" button.

　　while(1)

　　{

　　// Did the connection fail?

　　if( connection_status () != CONNECTION_NORMAL )

　　{

　　break;

　　}

　　// Sleep for 10 seconds

　　sleep (10);

　　}

　　// If this is reached, then the ‘break‘

　　// was triggered from inside the while loop

　　// So here we can log, or perform any other tasks

　　// we need without actually being dependent on the

　　// browser.

　　?>
