Add a new user from application php

Here is an example of how to add a new user from a PHP application:

<?php

// Connect to the database
$conn = mysqli_connect("localhost", "username", "password", "database_name");

// Check connection
if (!$conn) {
    die("Connection failed: ". mysqli_connect_error());
}

// Get the user data from the form
$username = $_POST['username'];
$email = $_POST['email'];
$password = $_POST['password'];

// Hash the password
$password_hash = password_hash($password, PASSWORD_DEFAULT);

// Insert the user into the database
$sql = "INSERT INTO users (username, email, password) VALUES ('$username', '$email', '$password_hash')";
if (mysqli_query($conn, $sql)) {
    echo "User added successfully!";
} else {
    echo "Error adding user: ". mysqli_error($conn);
}

// Close the connection
mysqli_close($conn);

?>

This code assumes that you have a table called users with columns username, email, and password. It also assumes that you are using the mysqli extension to interact with the database.

Here's how the code works:

It connects to the database using the mysqli_connect function.
It checks if the connection was successful, and if not, it dies with an error message.
It gets the user data from the form using the $_POST superglobal.
It hashes the password using the password_hash function.
It inserts the user into the database using the INSERT statement.
It checks if the insertion was successful, and if not, it echoes an error message.
It closes the connection using the mysqli_close function.

Note that this is just an example, and you should adjust the code to fit your specific needs. You may also want to add additional validation and security measures to ensure that the user data is valid and secure.
