How can a beginner in PHP programming effectively learn to create a self-entry database system for a website?

To create a self-entry database system for a website as a beginner in PHP programming, you can start by learning the basics of PHP and MySQL. You will need to understand how to connect to a database, create tables, insert data, and retrieve data using PHP. Additionally, you can use HTML forms to allow users to input data that will be stored in the database. 

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

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

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

// Create a form for users to input data
echo "<form method='post' action=''>
        <input type='text' name='data'>
        <input type='submit' value='Submit'>
      </form>";

// Insert data into the database
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $data = $_POST['data'];

    $sql = "INSERT INTO table_name (column_name) VALUES ('$data')";

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

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