PHP CURL w/o waiting for response

[Judahnator]

I am writing an API, and i need it to ping another server but not wait for a response.

 

The API I am writing must be as low-latency as possible, and the next server it sends a request to needs several seconds, sometimes even a full minute, to finish its task. This second script does not generate any output, so waiting for the servers response would only waste time.

 

How could i use CURL (or whatever) to do this? I have read that it is possible, however i cannot seem to find out how its done.

 

 

Thanks in advance!

What language are you using?

What language are you using?

There's no good way to do this, as php is (by design) a blocking language. Which means it will wait for the function to finish before continuing.

Some suggestions include:

1. Lower the curl timeout opt to something very low.

2. Use a socket to generate the http request manually, and then close the socket after opening.

PHP wasn't designed. That would imply that some thought was actually put into the language.

Have you tried with exec + nohup ?

 

something like:

exec("nohup ping.php > /dev/null 2>&1 &");

 

its not super optimized and bit heavy on resources, but as said before php is a blocking language, so there is no perfect solution.

Eww no. Never use exec. Or shell_exec. Or passthru. Or any of those functions. They're almost never necessary.

Thanks for that, i ended up going the socket route.
