How can PHP developers ensure flexibility in pagination scripts that dynamically generate page numbers based on database queries?

To ensure flexibility in pagination scripts that dynamically generate page numbers based on database queries, PHP developers can create a reusable function that calculates the total number of pages based on the total number of records in the database. This function can be called whenever pagination is needed, allowing for easy updates to the pagination logic without duplicating code. 

<?php

function calculateTotalPages($totalRecords, $recordsPerPage) {
    return ceil($totalRecords / $recordsPerPage);
}

// Example usage:
$totalRecords = 100;
$recordsPerPage = 10;
$totalPages = calculateTotalPages($totalRecords, $recordsPerPage);

echo "Total pages: " . $totalPages;

?>
