Fastest way to post variables to a url

[sidsel]

Currently I call a thirdparty script using fsockopen with a get method but it seems a little slow. I tried with curl and it's even slower.

If I don't care about the response but just want to fire off a url with some variables what is the fastest way to do it? It can be either get or post method.

if you don't care what the remote script returns then call it in the background with exec()

How would I do that? With curl or how?
