PHP referral link assistance

[system]

I am trying to get this code to pull from my url when the ID is placed in the URL with the URL extension
.php?ID=123456

<?php?>

$id=$GET [‘id’];

print"<a href=“http://help.com/join.php?id=$id”>";
?>

I dont think I have the PHP code correct. Thanks for any help

PHP is case sensitive. The id’s are entirely different.
[php].php?ID=123456 // uppercase[/php]
[php]$id=$GET [‘id’]; // lowercase[/php]

Use one or the other.
Hope that helps,
