How to implement scheduled (timed) tasks in PHP

Sometimes in order to adjust the interface regularly, the program needs to run automatically. From the Internet search, there are two ways to achieve this 1. ignore_user_abort() The ignore_user_abort() function can be used with set_time_limit(0) and sleep($interval) to realize automatic program update. Example: (As long as the following page is running, the program will continue to run even after the browser is closed)

//Even if the Client is disconnected (such as closing the browser), the PHP script can continue to execute.
ignore_user_abort();
//The execution time is unlimited. The default execution time of PHP is 30 seconds, through set_time_limit (0) The program can be executed without limit
set_time_limit(0);
// Run every 5 minutes
$interval=60*5;
do{
$url = “http://www.yexiwei.com ”;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 2);
$result = curl_exec( $ch);
curl_close($ch);
// Wait for 5 minutes
sleep($interval);
}while(true);
