没有 cron 的 PHP 调度程序

发布于 2025-01-04 18:00:08 字数 626 浏览 4 评论 0原文

我想每 5 分钟运行一次 php 脚本。这是我的 PHP 代码。

function call_remote_file($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);   
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
}
set_time_limit(0);

$root='http://mywebsiteurl'; //remote location of the invoking and the working script

$url=$root."invoker.php";
$workurl=$root."script.php";

call_remote_file($workurl);//call working script
sleep(60*5);// wait for 300 seconds.
call_remote_file($url); //call again this script

我运行这段代码一次。即使我关闭整个浏览器窗口，它也能完美运行。

问题是如果我关闭系统的互联网连接，系统就会停止工作。

如何解决这个问题。请帮帮我。

I want to run my php script for every 5 minutes. Here is my PHP code.

function call_remote_file($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);   
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
}
set_time_limit(0);

$root='http://mywebsiteurl'; //remote location of the invoking and the working script

$url=$root."invoker.php";
$workurl=$root."script.php";

call_remote_file($workurl);//call working script
sleep(60*5);// wait for 300 seconds.
call_remote_file($url); //call again this script

I run this code once. It works perfectly, even after i close the entire browser window.

The problem is the stops working if i turn of my system's internet connect.

How to solve this problem. Please help me out.

虽然我真的不建议对一些关键的事情这样做（你会遇到稳定性问题），但这可能有效：

function call_remote_file($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);   
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
}
set_time_limit(0);


$root='http://mywebsiteurl'; //remote location of the invoking and the working script

$url=$root."invoker.php";
$workurl=$root."script.php";

while(true)
{
    call_remote_file($workurl);//call working script
    sleep(60*5);// wait for 300 seconds.
}

另一种方法是使用 exec() 从命令行调用它：

function call_remote_file($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);   
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
}
set_time_limit(0);


$root='http://mywebsiteurl'; //remote location of the invoking and the working script

$url=$root."invoker.php";
$workurl=$root."script.php";

call_remote_file($workurl);//call working script
sleep(60*5);// wait for 300 seconds.
exec('php ' . $_SERVER['SCRIPT_FILENAME']);

如果可能的话，你真的应该使用 cron 。

While I wouldn't really recommend doing this for something critical (you're going to have stability issues), this could work:

function call_remote_file($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);   
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
}
set_time_limit(0);


$root='http://mywebsiteurl'; //remote location of the invoking and the working script

$url=$root."invoker.php";
$workurl=$root."script.php";

while(true)
{
    call_remote_file($workurl);//call working script
    sleep(60*5);// wait for 300 seconds.
}

Another way would be to call it from the command line using exec():

function call_remote_file($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);   
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
}
set_time_limit(0);


$root='http://mywebsiteurl'; //remote location of the invoking and the working script

$url=$root."invoker.php";
$workurl=$root."script.php";

call_remote_file($workurl);//call working script
sleep(60*5);// wait for 300 seconds.
exec('php ' . $_SERVER['SCRIPT_FILENAME']);

You should really use cron though if at all possible.
