How can PHP variables be properly declared and displayed within an HTML table?

To properly declare and display PHP variables within an HTML table, you can use PHP code to echo the variables within the table cells. You can declare the variables before the HTML code and then use them within the table structure to display their values dynamically.

<?php
// Declare PHP variables
$name = "John Doe";
$age = 30;
$email = "john.doe@example.com";
?>

<table>
    <tr>
        <td>Name:</td>
        <td><?php echo $name; ?></td>
    </tr>
    <tr>
        <td>Age:</td>
        <td><?php echo $age; ?></td>
    </tr>
    <tr>
        <td>Email:</td>
        <td><?php echo $email; ?></td>
    </tr>
</table>
