How can PHP be utilized to dynamically display content on a website based on user attributes stored in a MySQL database?

To dynamically display content on a website based on user attributes stored in a MySQL database, you can use PHP to query the database for the user's attributes and then use conditional statements to display different content based on those attributes. 

<?php
// Connect to MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Query database for user attributes
$user_id = $_SESSION['user_id'];
$sql = "SELECT * FROM users WHERE id = $user_id";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    $row = $result->fetch_assoc();
    // Display content based on user attributes
    if ($row['attribute'] == 'value1') {
        echo "Content for users with attribute value1";
    } elseif ($row['attribute'] == 'value2') {
        echo "Content for users with attribute value2";
    } else {
        echo "Default content for users";
    }
} else {
    echo "User not found";
}

$conn->close();
?>
