To better understand, use a simple code from your self!
There are different ways to pass a variable from a page to another.
The easiest method I guess, is to send the variables (in a GET method)
via URL.
so
from the first page, call the second page with a ling like
second.php?variable=value
You can then read the value of the variable by
echo $_GET["variable"]; // will print "value"
2 other methods are:
2. POST Method (forms with post)
3. Sessions or Cookies
Good luck
