Variable parsing & Safe Mode

Hi, I was wondering if anyone has a PHP solution for this problem. 1. I need to be able to capture all variables passed from a form. The problem is that I may not know all the variables. If known, I can access the variables with a $varname. I am trying to find a way to do this if the variable is unknown. I do not want to use PERL (for this solution) although I know it can be done. 2. We use RedHat 6.2, MySQL, PHP 3.x and have 5 developers. Each logs in under their own name. They are part of the same group (website). All of the websites are stored under the /www/sitename directory. All pages are owned by Webdude and group .website If a developer modifies an existing page, there is not a problem. However, if they create a new page it sets the ownership to them and then (seemingly randomly) when trying to access the page we get a safe mode violation. Note: most access the pages via Homesite connected thru a SMB connection. e.g. the linux box has an SMB point called www, the developers connect (via windows 2000/NT) and map the drive. All changes are using Homesite. To fix the problem, we have to set the owner, group, and permissions. Then it is fine. Any ideas? Thanks, Dave
