OK, I'm building a Web-based game. In order to utilize certain functions I always wanted to have, I need to use PHP. No big deal, just another language to learn. Now, I'm trying to set up variables that can be passed from page to page. I assume it works, but I'd never know: the darn echo won't work.
I have set up two pages for testing PHP: test1 and test2. I'm setting up a health system, and want to remove 25 health. OK, my code is:
test1.php
test2.php:
OK, I get no errors, but I can't get the variable to echo. If I put the variable in quotes, the ECHO works, but obviously it's not the variable I see. If I set up the code nice and pretty, I can't see any numbers. What am I doing wrong?
