不使用 CRON 调度脚本

I found another solution online that has to do with sockets. Just wanted to get everyones take on this, and tell me if this is a good or bad idea. Sounds like it works well.

想法?

//Open socket connection to cron.php
$socketcon = fsockopen($_SERVER['HTTP_HOST'],80,$errorno,$errorstr,10);
if($socketcon) {
$socketdata = "GET /cron.php HTTP 1.1
Host: ".$_SERVER['HTTP_HOST']."
Connection: Close

";
fwrite($socketcon,$socketdata);
//Normally you would get all the data back with fgets and wait until $socketcon reaches feof.
//In this case, we just do this:
fclose($socketcon);
} else {
//something went wrong. Put your error handler here.
}

cron.php:

//This script does all the work.
sleep(200);
//To prove that this works we will create an empty file here, after the sleep is done.
//Make sure that the webserver can write in the directory you're testing this file in.
$handle = fopen('test.txt','w');
fclose($handle);
