I would just like to ask , I created a input textbox and place the value of it in a variable. I already used it in my page#1. I want to used it in page#2 but I can't use it. It doesn't display the output that I want. I already tried making it a global variable but it also doesn't work. I'll wait for your replies thanks.
assuming page 1 posts to page 2, it will be available in either $POST or $GET global array in page 2
If you want to use the same variable across pages, you should look into using sessions and the $_SESSION array. If you just want to transmit the value via the form submission from the first page to the second, then do as Dagon suggests.
