Serious problem with setcookie

I have a problem with my set cookie function: Here is the code (all of it) #!/usr/local/bin/php <?

                      if (! $SID) {
                      if (! $SessionID) {
                      // Check for a SessionID cookie, and assign one if needed
                      $temp1=date("U");
                      $temp2=getmypid();
                      $SessionID="Zappy_".strval($temp1).strval($temp2).str $SessionID="Zappy_".strval($temp1).strval($temp2).strval(Rand()%1000);
                      $timeid=time()+60*60*24;
                      // $path_str = getenv("HTTP_HOST");
                      // Cookie is date + process number + random number
                      // Cookie will expire in one day (60 sec * 60 min * 24 hours)

                      SetCookie("SessionID",$SessionID,time()+60*60*24,"/");
                      // header("Set-Cookie:SessionID=$SessionID;domain=$path_str;expire=$timeid;path =/");
                      }
                      } else {
                      $SessionID = $SID;
                      }
                      // END OF COOKIE CHECK

?> ERROR I get is.... "sorry header has allready bene sent' This works on another server I have. One running on PHP Version 3.0.12 - works One running on PHP Version 3.0.15 - failed the one on PHP Version 3.0.12 does not need the #!/usr/local/bin/php part is just runs php, and php3 (plus what ever i tell it to parse in the .htaccess file) the one running Version 3.0.15 does need the #!/usr/local/bin/php at the top.. why I do not know. it is just what costomer support told me to use to have the server parse a php page. when it is not used the server does not parse the php in teh scripts and will only read the html. like stated above issue is i can run PHP on both servers.. i can setcookie with that script i provided on the first but not the second. the second one give me the "header allready sent..' any ideas.
