What are the key components needed to create a basic forum using PHP?

To create a basic forum using PHP, you will need to have a database to store user information, posts, and comments. You will also need to create PHP scripts to handle user registration, login, posting, and commenting functionalities. Additionally, you will need to design the forum layout using HTML and CSS to display the forum content. 

<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "forum";
$conn = new mysqli($servername, $username, $password, $dbname);

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

// Create a table for storing forum posts
$sql = "CREATE TABLE posts (
    id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    title VARCHAR(100) NOT NULL,
    content TEXT NOT NULL,
    user_id INT(6) UNSIGNED,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    FOREIGN KEY (user_id) REFERENCES users(id)
)";

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

// Close the database connection
$conn->close();
?>
