I am trying to understand what is so special about the use of arrays when the output could just as well be written in HTML.

I am trying to understand the dynamical function of arrays with regards to user input.

<form action="buy_snacks.php" method="post">
<select multiple name="snacks[ ]">
<option value="coke">CocaCola</option>
<option value="popcorn">Popcorn</option>
<option value="peanuts">Peanuts</option>
</select>
</form>

<?php
$snacks = $_POST['snacks'];
// Note that $snacks will be an array.
foreach ($snacks as $s) {
echo "$s<br />";
}
?>

for the above example it would just output
Cola cola, popcorn and peanuts.

wouldnt it be easier to just write it in HTML
