How can PHP be used to create new users in a MySQL database?

To create new users in a MySQL database using PHP, you can use the mysqli extension to connect to the database and execute an INSERT query with the user's information. 

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

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

// Insert new user into database
$username = "newuser";
$password = "newpassword";
$email = "newuser@example.com";

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

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

$conn->close();
?>
