Say I have a file function.php that is required by another file page.php. I want the file to act as
an include file like in C++. If I use define() and defined() I can tell whether the page is up and
in use. Can I use exit to keep PHP from running the rest of that page if the constant for that page
is already in use? I.e the following:
<PRE>
<SCRIPT LANGUAGE="PHP">
if (defined("MY_PAGE_CONST","YES"))
{
exit();
}
define("MY_PAGE_CONST","YES");
.../* Rest Of Page */ ...
</SCRIPT>
</PRE>
What can I use to make that work in the case the a page is included more than once?
