<select name="products[]" multiple>

use

<select name="products" multiple>

its not an array, until its posted

Your php code is incorrect and needs quotes inside the array. So the correction is the following:

<html>
<head>
<title>READING IMPUTS FROM THE FORM </title>
</head>
<body>
<?php
echo "<p><b>YOUR NAME IS: </b>".$_POST['user']."</p>";
echo "<p><b>YOUR ADDRESS IS: </b>".$_POST['address']."</p>";
echo "<p><br>YOUR PRODUCT CHOICES ARE:<br></p>";
if(!empty($_POST['products'])){
echo "<ul>";
foreach($_POST['products'] as $value) {
echo "<li>$value";
}
echo "</ul>";
}
?>
</body>
</html>

And please use code tags as it makes the code easier to read.
