What are the potential challenges of implementing a pagination function in PHP when dealing with unique IDs in a database?

When dealing with unique IDs in a database, one potential challenge of implementing a pagination function in PHP is ensuring that the pagination links are generated correctly based on the unique IDs. To address this issue, you can use the LIMIT and OFFSET clauses in your SQL query to fetch a specific range of records based on the unique IDs.

// Assuming $perPage is the number of items to display per page
// Assuming $currentPage is the current page number

$offset = ($currentPage - 1) * $perPage;

$query = "SELECT * FROM your_table ORDER BY unique_id LIMIT $perPage OFFSET $offset";
// Execute the query and display the results
