PHP-FPM - 限制执行时间，优雅停止

Question

So I have, in my application, some third-party calls to webservices.

These services can take, on peak times, a lot of time to respond, such that the value I defined for request_terminate_timeout on my PHP-FPM setup is reached. Script is then brutally aborted, and I cannot make use of register_shutdown_function to attempt a cleanup of the request.

Is there any PHP/PHP-FPM setting I'm not aware of that could limit the total execution time of a request? A "graceful" way to handle PHP-FPM termination?

• max_execution_time only takes into account time spent in PHP, which in my case is not the cause of long-running scripts
• Using pcntl calls, for web requests, doesn't seem such a good idea.

Answer 1

For a long-polling requests I would suggest to use cron/stack approach.

Question, why it was stopped could be addressed to your Apache/nginx server:

proxy_connect_timeout 500;
proxy_send_timeout 500;
proxy_read_timeout 500;

Also, you could use their triggers to handle timeout errors.

Answer 2

try setting the max_execution_time and catch the error

<?php
function shutdown()
{
    $a=error_get_last();
    if($a==null) {
        echo "No errors";
    } else {
        gracefully_shutdown();
    }
}
register_shutdown_function('shutdown');
ini_set('max_execution_time', 10 ); //set to 10 seconds

// do some works here
do_some_works();

?>
