What resources or learning materials would you recommend for beginners looking to understand the relationship between PHP, MySQL, and HTML?

To understand the relationship between PHP, MySQL, and HTML, beginners can start by learning the basics of each language individually. They can then explore how PHP can be used to interact with a MySQL database to retrieve or store data, which can then be displayed on a webpage using HTML.

<?php
// Connect to MySQL 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);
}

// Retrieve data from MySQL database
$sql = "SELECT * FROM table";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data in HTML table
    echo "<table>";
    while($row = $result->fetch_assoc()) {
        echo "<tr><td>" . $row["column1"] . "</td><td>" . $row["column2"] . "</td></tr>";
    }
    echo "</table>";
} else {
    echo "0 results";
}

$conn->close();
?>
