Basicly I have a bunch of links on a page and I will use something like this
<?PHP echo $SITE_PATH ?>
Many many times on the same page but it will show a Notice in PHP for doing so.
I know you are supposed to use things like isset() but would I really need to use it every time I call?
<?PHP echo $SITE_PATH ?>
--- EDIT :
If I switch to using a defined variable, then the notices seem to go away
