How can PHP beginners effectively handle and display dynamic data on a webpage?

PHP beginners can effectively handle and display dynamic data on a webpage by using PHP to fetch data from a database, process it, and then display it on the webpage using HTML. They can achieve this by using functions like mysqli_query() to retrieve data from a database and then using loops like foreach to iterate over the data and display it dynamically on the webpage.

<?php
// Connect to database
$connection = mysqli_connect('localhost', 'username', 'password', 'database_name');

// Query to fetch data from database
$query = "SELECT * FROM table_name";
$result = mysqli_query($connection, $query);

// Display data on webpage
echo "<ul>";
while($row = mysqli_fetch_assoc($result)) {
    echo "<li>{$row['column_name']}</li>";
}
echo "</ul>";

// Close database connection
mysqli_close($connection);
?>
