if(isset($_POST['dance']))          $dance = 'Dance Lessons, ';
if(isset($_POST['vacation']))       $vacation   = 'Vacation planning, ';
if(isset($_POST['group']))      $group = 'Group Vacation, ';
if(isset($_POST['inprivate']))      $inprivate = 'Private Vacation, ';
if(isset($_POST['land']))           $land = 'Land purchase/lease';

@$interest = $accomodation.$dance.$vacation.$group.$inprivate.$land;
@echo $string;

*sorry for such dumb question, it’s been so long i didn’t touch native PHP programming

Answer 1

$string = preg_replace('/\s*,\s*$/', '', $string);

or, way cooler:

$string = rtrim($string, " ,");

Note that it does not matter the order of the characters in the pattern string.

@You last update.
This changes some things. You could put all your variables in one array and then implode it. Like so:

$items = array();
$items[] = $accomodation = 'Accomodation';
$items[] = $dance = 'Accomodation';
...
$result = implode(', ', $items)
