title: Why is there an t string syntax error?
body: <p>I dont understand why this is giving me an t string syntax error. It looks to me correct! Can somebody please help me out? I am few weeks into my php learning attempt and just trying to make sense of this jumble. I know this is something incredibly stupid but I cannot figure it out!</p>
  
  <pre><code>&lt;?php 
  // set up some variables 
  // the toys 
  $item1 = "X−ray specs"; 
  $item2 = "Watch with built−in poison gas canister";
  $item3 = "Exploding chewing gum"; 
  // the price 
  $item1_cost = 100; $item2_cost = 250; $item3_cost = 32; 
  // the amount
  $item1_qty = 1; $item2_qty = 2; $item3_qty = 15; 
  // calculate cost for each item 
  $item1_total = $item1_cost * $item1_qty;
  $item2_total = $item2_cost * $item2_qty; 
  $item3_total = $item3_cost * $item3_qty; 
  
  // calculate grand total
  $grand_total = $item1_total + $item2_total + $item3_total; 
  //special secret agent discount − 10% 
  $discount = 10; 
  // which reduces total bill amount 
  $amount = ($grand_total * 10)/100;
  // the bottom line 
  
  $net_total = $grand_total − $amount;
