Help rtrim would not work whatever I do. I also tried to add whitespace after "," like it was on one of the topics i searched here

$this->items = array();
foreach ($items as $v) {
   $this->items[$v['id']] = $v;
rtrim($xcount, ",");

    The rtrim() returns a value and does not modify the original value. Please use it this way:

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

    From the rtrim():

    This function returns a string with whitespace (or other characters) stripped from the end of str.
