Teus. whatever it is that your trying to do, it sounds like one of two things: 1. you have hosting that is unsuitable for your needs 2. you are tackling the problem incorrectly at any rate, as far I'm concerned, you should never have a long running php process via a web server. (obviously this is the point that someone posts a brilliant use case to prove me wrong ;-) could you detail what is is you're actuallt trying to do, chances are people have: a. got a better alternative b. already invented the particular wheel you're trying to build c. you really do need shell (or even just control panel) access to run a cron job > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
