What are some strategies for ensuring that PHP-generated HTML tables are valid and well-structured for display in a web browser?

When generating HTML tables in PHP, it is important to ensure that the tables are well-structured and valid to display correctly in a web browser. One way to achieve this is by properly formatting the table markup with the correct HTML tags and attributes. Additionally, using CSS for styling can help improve the visual appearance of the table.

<?php
// Sample PHP code to generate a well-structured HTML table

// Data for the table
$data = array(
    array("Name", "Age", "Email"),
    array("John Doe", 30, "john.doe@example.com"),
    array("Jane Smith", 25, "jane.smith@example.com")
);

// Start the table
echo "<table>";

// Loop through the data and generate table rows
foreach ($data as $row) {
    echo "<tr>";
    foreach ($row as $cell) {
        echo "<td>" . $cell . "</td>";
    }
    echo "</tr>";
}

// End the table
echo "</table>";
?>
