In terms of performance and efficiency, what changes can be made to the PHP code to improve the rendering of the table and reduce unnecessary iterations or checks?

To improve the rendering of the table and reduce unnecessary iterations or checks, we can optimize the code by reducing the number of nested loops and minimizing redundant checks. One way to achieve this is by pre-processing the data before rendering the table to eliminate the need for repeated calculations or checks during the rendering process. 

<?php
// Pre-process data to reduce unnecessary iterations or checks
$processedData = [];

foreach ($data as $row) {
    $processedData[$row['id']] = $row;
}

// Render the table using the pre-processed data
echo '<table>';
foreach ($processedData as $row) {
    echo '<tr>';
    echo '<td>' . $row['id'] . '</td>';
    echo '<td>' . $row['name'] . '</td>';
    echo '<td>' . $row['age'] . '</td>';
    echo '</tr>';
}
echo '</table>';
?>
