 <?php 
    $url = $_POST['new_url'];
    $t_d = $_POST['t_d'];
    $t_t = $_POST['t_t'];
    $str = $url.":{"."domain:".$t_d.","."template:".$t_t."},";
          if (isset($url)) 
          {
            array_push($list, $str);
          }
    ?>

If it's really a json array you should try decode the string into array:

<?php 
$decoded_list = json_decode($list, true); 
?>

then just push the new element into the array? Finally you can do

<?php 
$list = json_encode($decoded_list); 
?>
