RE: [PHP] Multiple Threads?
I think what I'm going to end up doing, is using a perl CGI script to do this part. I /know/ perl can do it easily, and I won't have to hack together my own threading code. Thanks for the suggestions though.

RE: [PHP] Multiple Threads?
PHP can fork but the docs say not to do it in a web server environment. basically, it's only usable on *nix machines and in a shell scripting environment. =C= * * Cal Evans * Journeyman Programmer * Techno-Mage * http://www.calevans.com * -Original Message- From: Matthew Walker [mailto:[EMAIL PROTECTED]] Sent: Saturday, April 13, 2002 10:26 PM To: [EMAIL PROTECTED] Subject: [PHP] Multiple Threads?
