What are the potential drawbacks of outsourcing registration completely to PHP files without using MySQL in a large-scale project?

One potential drawback of outsourcing registration completely to PHP files without using MySQL in a large-scale project is the lack of scalability and performance issues. Storing user data directly in PHP files can lead to slower retrieval times and difficulties in managing and querying data efficiently. To address this issue, it is recommended to use a database management system like MySQL to handle user registration and data storage. 

// Sample PHP code snippet using MySQL for user registration
<?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);
}

// Insert user data into MySQL database
$username = "john_doe";
$email = "john.doe@example.com";
$password = "password123";

$sql = "INSERT INTO users (username, email, password) VALUES ('$username', '$email', '$password')";

if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

$conn->close();
?>
