Found something interesting. The following define:
<?php
define("THIS-IS-A-TEST","This is a test");
echo THIS-IS-A-TEST;
?>
Will return a '0'.
Whereas this:
<?
define("THIS_IS_A_TEST","This is a test");
echo THIS_IS_A_TEST;
?>
Will return 'This is a test'.
This may be common knowledge but I only found out a few minutes ago.
[EDIT BY danbrown AT php DOT net: The original poster is referring to the hyphens versus
underscores. Hyphens do not work in defines or variables, which is expected behavior.]
