PHP：了解CURL超时

Question

From a php page, i have to do a get to another php file. I don't care to wait for the response of the get or know whether it is successful or not.

The file called could end the script also in 5-6 seconds, so i don't know how to handle the get timeout considering what has been said before.

The code is this

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://mywebsite/myfile.php'); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, false);
curl_setopt($ch, CURLOPT_TIMEOUT, 1);
$content = trim(curl_exec($ch));
curl_close($ch);

Answer 1

对于第一个任务（不需要等待响应的地方），您可以启动新的后台进程，然后在该进程下面编写代码，该代码将在另一个页面上重定向您。

Yeah, you definitely shouldn't be creating a file on the server in response to a GET request. Even as a side-effect, it's less than ideal; as the main purpose of the request, it just doesn't make sense.

If you were doing this as a POST, you'd still have the same issue to work with, however. In that case, if the action can't be guaranteed to happen quickly enough to be acceptable in the context of HTTP, you'll need to hive it off somewhere else. Eg make your HTTP request send a message to some other system which then works in parallel whilst the HTTP response is free to be sent back immediately.
