What additional components besides PHP are necessary to create a disposable email system?

To create a disposable email system, in addition to PHP, you will need a web server (such as Apache or Nginx), a database system (such as MySQL or PostgreSQL) to store email addresses and messages, and possibly a front-end framework like Bootstrap for designing the user interface.

// PHP code snippet for creating a disposable email system
// This is a basic example and should be extended for production use

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "disposable_emails";

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

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

// Create a table to store disposable email addresses
$sql = "CREATE TABLE disposable_emails (
    id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    email VARCHAR(50) NOT NULL,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
)";

if ($conn->query($sql) === TRUE) {
    echo "Table disposable_emails created successfully";
} else {
    echo "Error creating table: " . $conn->error;
}

$conn->close();
