What steps can be taken to ensure that PHP-generated HTML code displays correctly, especially when passing values from a database query?

When passing values from a database query to PHP-generated HTML code, it's important to ensure that the data is properly escaped to prevent any potential security vulnerabilities or display issues. One way to do this is by using PHP's htmlspecialchars() function to encode special characters in the data before outputting it in the HTML code. 

// Example code snippet to display database query results safely in HTML
$query = "SELECT * FROM table_name";
$result = mysqli_query($connection, $query);

while($row = mysqli_fetch_assoc($result)) {
    $name = htmlspecialchars($row['name']);
    $email = htmlspecialchars($row['email']);

    echo "<p>Name: $name</p>";
    echo "<p>Email: $email</p>";
}
