note 25599 added to function.exec

I am running a WIMP configuration and I want to use exec() to call mysql.exe via my PHP script to run a big sql script in the background. The PHP script executes the sql script via mysql.exe but my PHP script hangs until the mysql process has finished. Does anybody know how I can run the exec() command totally in the background on a WIMP system ? (I tried a lot with "2>1&" and "cmd/c" etc.) -- http://www.php.net/manual/en/function.exec.php http://master.php.net/manage/user-notes.php?action=edit+25599 http://master.php.net/manage/user-notes.php?action=delete+25599 http://master.php.net/manage/user-notes.php?action=reject+25599
