How can PHP beginners improve their understanding of table structures and data output in web development projects?

PHP beginners can improve their understanding of table structures and data output in web development projects by practicing creating and manipulating tables using PHP and MySQL. They can also study and experiment with different functions and techniques for fetching and displaying data from a database in a tabular format. Additionally, utilizing frameworks like Laravel or CodeIgniter can provide beginner-friendly tools and resources for working with tables and data output.

<?php
// Connect to the 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);
}

// Fetch data from a table and display it in a HTML table
$sql = "SELECT * FROM table_name";
$result = $conn->query($sql);

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

$conn->close();
?>
