我如何在这种情况下使用if / then / else？

Question

I am having problem using the if/then/else statements.

here is my context:

$email = trim($_POST['email']);
$name = trim($_POST['name']);
$lname = trim($_POST['lname']);
$order = trim($_POST['order']);
$tel = trim($_POST['tel']);
$comments = trim($_POST['comments']);
$op ="0000-0000-0000";
$om ="[e-mail]";
$bronze = "180 EGP/yr";
$silver ="280 EGP/yr";
$gold ="350 EGP/yr";
$plat ="420 EGP/yr";
$free ="EGP/yr";


if ($order == 'bronze') {
    echo "Please notice that your order will cost $bronze";
}

Now how can I do it again with $silver ? And so on like for silver, gold, plat and free or even if I wanna add more.

The switch statement would actually be a better fit for this situation:

<?php
$email = trim($_POST['email']);
$name = trim($_POST['name']);
$lname = trim($_POST['lname']);
$order = trim($_POST['order']);
$tel = trim($_POST['tel']);
$comments = trim($_POST['comments']);
$op ="0000-0000-0000";
$om ="[e-mail]";
$bronze = "180 EGP/yr";
$silver ="280 EGP/yr";
$gold ="350 EGP/yr";
$plat ="420 EGP/yr";
$free ="EGP/yr";


switch ($order) {
  case  'bronze':
    echo "Please notice that your order will cost $bronze";
    break;
  case  'silver':
    echo "Please notice that your order will cost $silver";
    break;
  case  'gold':
    echo "Please notice that your order will cost $gold";
    break;
  case  'plat':
    echo "Please notice that your order will cost $plat";
    break;
  case  'free':
    echo "Please notice that your order will cost $free";
    break;
  default:
    echo "Please choose a service package.";
    break;
}
