title: PHP Function to return string
body: <p>I am fairly new to PHP. I have a function which checks the cost of price. I want to return the variable from this function to be used globally:</p>
  
  <pre><code>&lt;?
  function getDeliveryPrice($qew){
      if ($qew=="1"){
          $deliveryPrice="60";
      } else {
          $deliveryPrice="20";
      }
      return $deliveryPrice;                          
  }
  // Assuming these two next lines are on external pages..
  getDeliveryPrice(12);
  echo $deliveryPrice; // It should return 20
  
  ?&gt;
  </code></pre>
