Since it is a string, I think the easiest is to first convert it to an array, remove the value, and put it back together again:
$values = explode(',', $var2);
if (($key = array_search($var1, $values)) !== false) {
unset($values[$key]);
}
$var2 = implode(',', $values);
The part about deleting from the array is gratefully copied from this answer.

You can use a simple str_replace which uses regex:
<?php
$var2 = str_replace("%$var1%", "", $var2); //remove the element if it is inside
$var2 = str_replace("%,,%", ",", $var2); //Remove the ',' if it's needed
?>
