What are the potential pitfalls of trying to build a forum from scratch without prior understanding of PHP basics?

Building a forum from scratch without prior understanding of PHP basics can lead to numerous pitfalls such as security vulnerabilities, inefficient code structure, and difficulty in troubleshooting and maintaining the forum. To address these issues, it is crucial to first learn the fundamentals of PHP programming, including topics such as data handling, security best practices, and object-oriented programming. 

<?php
// Sample PHP code snippet demonstrating basic data handling and security best practices

// Sanitize user input to prevent SQL injection
$username = mysqli_real_escape_string($conn, $_POST['username']);
$password = mysqli_real_escape_string($conn, $_POST['password']);

// Hash the password before storing it in the database
$hashed_password = password_hash($password, PASSWORD_DEFAULT);

// Validate user input to ensure data integrity
if (empty($username) || empty($password)) {
    echo "Please enter both username and password";
} else {
    // Perform database operations here
}
?>
