Sure.
$footcontent was never passed or declared in your function.
echoing $footercontent will do nothing more than display whatever the value
of $footercontent is.
You need to call the function in your file.
myExit();
and one thing you can do is pass the value of $footercontent by placing it
in your function call.
// Declare Footer
$footercontent = 'End of my page';
myExit($footercontent);
then in your function you will need an instance of $footercontent.
function myExit(&$myfootercontent){
print("</table>$footercontent");
exit;
}
hope that helps.
