Your ifexists() function doesn't work for me in PHP 5.3. The caller's variables are not available in the function's local scope (see Variable scope), unless they are Superglobals or you fiddle with $GLOBALS, so $foo = "BABAR"; ifexists('foo'); will in general return null. (Italics are php.net chapters.)

now you will get "hello from"... what's the point? just check the value if( !empty($user) and !empty($location) ) echo "hello $user ..."
