Saving changes to a file

Hello, I am trying to make am admin page for a few other pages in PHP but I dont know how to save the changes made. ie. The page has a few checkboxes & select boxes that when changed, change some variables that are then used in other pages. However I want the changes in the admin page to be permanent, until they are changed again. Not just for that session or user, but if the change is made it stays changed until the administrator decideds to go back in and change it again. How do you save the changes in that file on the server, by just using a browser? -- Regards, YoBro ------------------------------------------------------------- DO NOT REPLY TO THIS VIA EMAIL PLEASE USE THE NEWSGROUP All emails sent to this address are automatically deleted.
