Challenge 3 — Solution

Task: Create an array of 5 favourite foods. Use foreach to echo each
one numbered (1. Pizza, 2. Sushi, etc.) — you'll need a counter
variable you increment yourself, since plain foreach on a simple array
doesn't give you a position number directly.

<?php
    $foods = ["Pizza", "Sushi", "Curry", "Tacos", "Ramen"];

    $number = 1;
    foreach ($foods as $food) {
        echo "$number. $food<br>";
        $number++;
    }
?>


Output:
1. Pizza
2. Sushi
3. Curry
4. Tacos
5. Ramen

Notes:
- $number is created and set to 1 before the loop starts, then
  incremented once per iteration inside the loop body - foreach itself
  has no built-in position counter for a plain indexed array.
- $foods as $food gives direct access to each value in turn, with no
  need to manually index into the array at all.
- An alternative would be to use the array's own real keys (0, 1, 2...)
  with foreach ($foods as $index => $food) and echo ($index + 1), but a
  separate counter is more explicit about what's actually being
  displayed to the user.
