In what scenarios does counting HTML tables make sense and how can it be effectively implemented?

Counting HTML tables can be useful when you need to dynamically generate tables and keep track of the number of tables being generated. This can be helpful for various purposes such as pagination, displaying a table count to the user, or for any other data manipulation needs. To implement this, you can use a simple PHP function that counts the number of table elements in the HTML content. 

<?php
$html = '<table><tr><td>Table 1</td></tr></table><table><tr><td>Table 2</td></tr></table><table><tr><td>Table 3</td></tr></table>';

function countTables($html) {
    $dom = new DOMDocument();
    $dom->loadHTML($html);
    $tables = $dom->getElementsByTagName('table');
    return $tables->length;
}

$tableCount = countTables($html);
echo "Total number of tables: " . $tableCount;
?>
