What are some recommended tutorials for creating a form in PHP that can write data to a database and allow for editing?

To create a form in PHP that can write data to a database and allow for editing, you will need to use HTML for the form structure and PHP for handling the form submission and database operations. You can use MySQL or any other database system to store the form data. It's important to sanitize and validate user input to prevent SQL injection and other security vulnerabilities. 

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

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

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

// Process form submission
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = $_POST['name'];
    $email = $_POST['email'];

    // Insert data into database
    $sql = "INSERT INTO users (name, email) VALUES ('$name', '$email')";
    if ($conn->query($sql) === TRUE) {
        echo "New record created successfully";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }
}

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

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    Name: <input type="text" name="name"><br>
    Email: <input type="email" name="email"><br>
    <input type="submit" value="Submit">
</form>
