如何使用PHP创建cron作业？

Question

I'm new to using cron job. I don't even know how to write it. I have tried to search from internet, but I still don't understand it well. I want to create a cron job that will execute my code every minute. I'm using PHP to create it. It is not working.

Example

run.php (Code that will be executed every minute)

<?php

echo "This code will run every minute";

?>

cron.php

<?php

$path = dirname(__FILE__);
$cron = $path . "/run.php";
echo exec("***** php -q ".$cron." &> /dev/null");

?>

Suppose that these two files are in the same folder.

Is the code that I did wrong? If wrong, please kindly tell me how to fix it.

Answer 1

Create a cronjob like this to work on every minute

*       *       *       *       *       /usr/bin/php path/to/cron.php &> /dev/null
