How can PHP developers ensure that the correct link is deleted when a submit button is clicked in a dynamically generated table?

When a submit button is clicked in a dynamically generated table, PHP developers can ensure that the correct link is deleted by passing the unique identifier of the link as a hidden input field in the form. This identifier can then be used to identify and delete the correct link when the form is submitted. 

<?php
// Assuming $links is an array of links with unique identifiers
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if (isset($_POST['delete_link'])) {
        $linkIdToDelete = $_POST['link_id'];
        
        // Delete the link with the specified ID from the $links array
        unset($links[$linkIdToDelete]);
        
        // Reindex the array to prevent gaps
        $links = array_values($links);
    }
}

// Display the dynamically generated table
echo '<form method="post">';
foreach ($links as $index => $link) {
    echo '<tr>';
    echo '<td>' . $link['name'] . '</td>';
    echo '<td>' . $link['url'] . '</td>';
    echo '<td><input type="hidden" name="link_id" value="' . $index . '"><input type="submit" name="delete_link" value="Delete"></td>';
    echo '</tr>';
}
echo '</form>';
?>
