How can the user ensure that the row numbers remain consistent even after sorting the entries?

When sorting entries in a table, the row numbers displayed may change as the order of the entries changes. To ensure that the row numbers remain consistent even after sorting, you can add a separate column in the table that displays the original row numbers before sorting. This way, the row numbers will always reflect the original order of the entries regardless of how they are sorted. 

// Display original row numbers in a table before sorting
echo "<table>";
echo "<tr><th>#</th><th>Name</th><th>Age</th></tr>";

// Array of entries
$entries = array(
    array("name" => "John", "age" => 25),
    array("name" => "Alice", "age" => 30),
    array("name" => "Bob", "age" => 22)
);

// Display original row numbers
foreach ($entries as $key => $entry) {
    echo "<tr><td>" . ($key + 1) . "</td><td>" . $entry['name'] . "</td><td>" . $entry['age'] . "</td></tr>";
}

echo "</table>";
