Viewing Data from the Database in PHP

Let's create a page show.php, where we can view the user's data formatted with a specific layout.

Let's assume we are given the following layout for this:

<div>
	<h1>user1</h1>
	<p>
		age: <span class="age">23</span>,
		salary: <span class="salary">400</span>
	</p>
</div>

Let the id of the user we want to view be passed via the GET parameter named id. Let's get it into a variable:

<?php
	$id = $_GET['id'];
?>

Let's form a query to get this user:

<?php
	$query = "SELECT * FROM users WHERE id=$id";
?>

Let's execute the query:

<?php
	$result = mysqli_query($link, $query) or die(mysqli_error($link));
?>

Let's write the user data into a variable:

<?php
	$user = mysqli_fetch_assoc($result);
?>

Let's output this data in our layout:

<div>
	<h1><?= $user['name'] ?></h1>
	<p>
		age: <span class="age"><?= $user['age'] ?></span>,
		salary: <span class="salary"><?= $user['salary'] ?></span>
	</p>
</div>

Implement the user view using the following layout:

<div>
	<p>
		name: <span class="name">user1</span>
	</p>
	<p>
		age: <span class="age">23</span>,
		salary: <span class="salary">400$</span>,
	</p>
</div>

On the page index.php, implement the output of links to view each of the users:

<a href="/en/show.php?id=1">user1</a>
<a href="/en/show.php?id=2">user2</a>
<a href="/en/show.php?id=3">user3</a>
