1. How do you pass variables between php files? Suppose I want to have an 'undo' function to undo the last transaction. I set a link with:
Is that right? If so, can I just access the variable from undo.php with no difficulties?
2. How would I code a .php file to refresh itself every minute? I want it to automatically update so that I can see team standings (in order of account balance).
3. Suppose I have a form called input.html, which posts to input.php, which inserts data into a table (or several tables). Is it possible that two people from different locations can access both of these files simultaneously? So that people can submit the form on different PC's, and the mySql will still work properly?
Thanks for the help,
