What are common mistakes beginners make when trying to implement pagination in PHP?

Common mistakes beginners make when implementing pagination in PHP include not properly calculating the total number of pages, not setting the correct limit and offset values for fetching data from a database, and not handling edge cases such as the first and last pages correctly. To solve these issues, make sure to calculate the total number of pages based on the total number of records and the limit per page, set the correct limit and offset values for fetching data, and handle edge cases in your pagination logic.

php 
// Calculate total number of pages
$total_pages = ceil($total_records / $limit);

// Set limit and offset values for fetching data
$offset = ($page - 1) * $limit;
$query = "SELECT * FROM table_name LIMIT $limit OFFSET $offset";

// Handle edge cases for pagination
if($page < 1){
    $page = 1;
} elseif($page > $total_pages) {
    $page = $total_pages;
}
