Just google the stream_set_blocking a while and see some code examples,
it's easy to use.

This is a bit over my head. Could you explain more or give me some links?

well right! Just forgot to use stream_set_blocking(..., ...) to set a stream non-blocking mode.

It's easy, you write a rest API to do the write staff, and in your main code , you just have to request the rest API and do not wait it to return
I don't know, if I get you right
- If you _provide_ an API. In that case the request should actually handle the request only and therefore there is no need to free the process from the burden to answer the request.
- If you _consume an API, than I'd recommend using non-blocking streams instead. There are much easier to handle.

But how should I do in the HTTP SERVER environment? I don't want php to wait until the file write is finished before the url is displayed. I've tried to use flush, ob_flush but that didn't work, possibly because I have session_start in the beginning of my code. Should I use exec to start a second php?

Child process should has the same environment as the parent process. I
don't see any thing wrong with your code.
I assume that you are using php to handle http request for the using of
$_GET , but I think it is wrong to use multi process in PHP in the HTTP
SERVER environment

Hi!
I've tried the following code but the $call variable is not available in the pcntl_fork child. Searching the web, I've found posts that claim that all variables defined before pcntl_fork are copied to the child. I've also found posts that claim that no variables are passed/copied to the child. So, which of them is true and how should I correct my code to make it work?
regards
Henrik
$call = str_replace('@@', '&', $_GET['call']);
if ($pid = pcntl_fork())
{
$previousCalls=file("calls.txt", FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
if (!in_array($call, $previousCalls))
{
file_put_contents("calls.txt", $call."\n", FILE_APPEND);
}
}
else
{
function displayUrl($url)
{
$ch = curl_init($url);
curl_setopt ( $ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$curlResult = curl_exec($ch);
curl_close($ch);
list($headers,$content) = explode("\r\n\r\n",$curlResult,2);
foreach (explode("\r\n",$headers) as $hdr)
{
if ($hdr != 'Transfer-Encoding: chunked')
{
header($hdr);
}
}
echo $content;
}
displayUrl($call);
}
