Declare and call the function

We output products from the $order array to the product page, but the product price and shipping cost were incorrectly displayed the same for all products. Why is this the case?

The problem is that we are only calculating the total price and shipping cost once for the product that is written to the $id variable in the script. Then substitute the same numbers for all products in the loop.

$id = $order[1];                       // We obtain the product ID
$price = get_product_price($id);       // We obtain the product price
$discount = get_product_discount($id); // We obtain the product discount
$final_price = $price - $discount;    // We calculate the final price

// We output the same price for all products
<?php foreach($order as $id): ?>
  ...
  <td><?= $final_price ?></td>
  ...
<?php endforeach; ?>

We need to calculate the price and shipping cost for each individual product. But let’s think about it before we merely transfer the calculations inside the loop. What if the web designer deletes something by mistake? Or what if you need to output data in several places?

There is a better way: use a function.

A function is a fragment of code that can be written once and then used when required.

Before using a function, you need to declare it using the function keyword. Then give the function a name, which must begin with a Latin character or underscore.

Write a set of parentheses after the function name, and then write the function body in curly braces. Inside the function body — that is, within the curly braces — is code that the function will execute.

function my_func() {
  muffin_log('I am the my_func function');
}

When a function is declared, PHP will remember it, but the code inside the curly braces is not executed. It’s like the “speed dial” feature on a smartphone. First, associate the number with a shortcut on the screen, and then press this shortcut to make a call. The same thing is true of functions. First associate the code fragment with the function name, and then call this function.

Write the function name and a set of parentheses in order to execute it.

my_func(); // Outputs: "I am the my_func function"

The function can be called any number of times. It can even call itself, which is known as recursion.

Create a function to calculate the total price of the product and practice calling it.

Dumpo temporarily removed part of the code from the script so that it wouldn’t bother us anymore.

      1. On line 6, declare a function for calculating the total price of the product: function get_final_price() { }.
      2. In the function body, use the muffin_log command to output the string 'Greetings from the function' to the console.
        Note how nothing yet appears in the console.
      3. Call this function below the declaration of the get_final_price function. Don’t forget about the parentheses!
        Please note that now the text has appeared in the console.
      4. On the next line, call the get_final_price function again. Please note that a second message has now appeared in the console.
