How to really limit the maximum execution time of a PHP script?

Question

PHP

Hello!

As you know, max_execution_time can limit the script execution time, however, if, for example, file_get_contents is called during execution, which will request a url that responds, for example, 100 seconds, then with max_execution_time 30 seconds, the script will still run for 100 seconds. This is actually stated in the PHP documentation.

Question: is it really possible to somehow limit the execution time in this case to 30 seconds, while not setting the file_get_contents context or setting the maximum time for sockets. That is, the unconditional termination of the script is of interest, regardless of what is in the code.

Thank you!

Answer 1

For php-fpm there is a request_terminate_timeout

The timeout for serving a single request after which the worker process will be killed. This option should be used when the 'max_execution_time' ini option does not stop script execution for some reason. A value of '0' means 'off'. Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
Default Value: 0

For apache, you can look towards TimeOut, but I'm not sure if this will work exactly as it should (haven't used apache for a long time).

register_tick_function will help solve this abstract problem

You can also set limits for file_get_contents
ini_set('default_socket_timeout', 30);

$ctx = stream_context_create(array('http'=>
    array(
        'timeout' => 1200,  //1200 Seconds is 20 Minutes
    )
));

echo file_get_contents('http://example.com/', false, $ctx);
