Re: Pass variable to pcntl_fork child

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 于 2014年07月02日 17:40, Uggla Henrik 写道:

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);
     }
