How can a beginner in PHP create a database for a website with specific search criteria and password-protected areas?

To create a database for a website with specific search criteria and password-protected areas, a beginner in PHP can use MySQL to create the database structure, implement SQL queries to retrieve data based on search criteria, and use PHP to handle user authentication for password-protected areas. 

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

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

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

// SQL query to retrieve data based on search criteria
$search_criteria = "example";
$sql = "SELECT * FROM table_name WHERE column_name = '$search_criteria'";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data
    while($row = $result->fetch_assoc()) {
        echo "Column1: " . $row["column1"]. " - Column2: " . $row["column2"]. "<br>";
    }
} else {
    echo "No results found";
}

// User authentication for password-protected areas
$password = "user_password";
if ($_POST["password"] == $password) {
    // Allow access to protected area
    echo "Welcome to the protected area!";
} else {
    // Deny access
    echo "Incorrect password. Access denied.";
}

$conn->close();
?>
