Sometimes in order to adjust the interface regularly, the program needs to run automatically. From the Internet, there are two ways to achieve this: 1. ignore_user_abort() The ignore_user_abort() function is combined with set_time_limit(0) and sleep($interval) to realize the automatic running and updating of the program.
  1. //Even if the Client is disconnected (such as closing the browser), the PHP script can continue to execute.
  2. ignore_user_abort();
  3. //The execution time is unlimited. The default execution time of PHP is 30 seconds. By set_time_limit(0) allows the program to execute without limit
  4. set_time_limit(0);
  5. // Run every 5 minutes
  6. $interval=60*5;
  7. do{
  8. $url = “http://www.xxx. con";
  9. $ch = curl_init();
  10. curl_setopt($ch, CURLOPT_URL, $url);
  11. curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  12. curl_setopt($ch, CURLOPT_TIMEOUT, 2);
  13. $result = curl_exec ($ch);
  14. curl_close($ch);
  15. // Wait for 5 minutes
  16. sleep($interval);
  17. }while(true);
