signal handling

Roman, Stut and Jochem, thanks for the comments and recommendations on the subject. I have installed my signal as pcntl_signal(SIGCHLD, SIG_IGN) without a specific function handler and it is closing child processes now. I could not use the pcntl_wait because it is available after PHP 5.0 i guess. -----Original Message----- From: Roman Neuhauser [mailto:neuhauser@sigpipe.cz] Sent: Friday, December 08, 2006 7:02 PM To: Jochem Maas Cc: php-general@lists.php.net Subject: Re: [PHP] signal handling # jochem@iamjochem.com / 2006-12-08 15:36:52 +0100: > Roman Neuhauser wrote: > > # manager@phidot.com / 2006-12-02 02:01:35 +0200: > >> [...] to write a simple socket server in PHP.
