function not printing

Just declare $tdValues as an array. $tdValues = array(); And instead of using the string concatenation operator .= to add to it, use the array append operator [].

    for($j = 0; $j < $totaltds; $j++){
        $line= '';
  
        /* build line data here */
        $tdValues[] = $line; // add a new element to the array.
    }
