What are common pitfalls when implementing paging in PHP arrays?

Common pitfalls when implementing paging in PHP arrays include not properly calculating the offset for pagination, not handling out-of-bounds page numbers, and inefficiently slicing the array for each page. To address these issues, it is important to accurately calculate the offset based on the current page number and limit, handle cases where the page number exceeds the total number of pages, and efficiently slice the array using array_slice(). 

// Sample PHP code snippet for implementing paging in PHP arrays

// Define the array to be paginated
$data = range(1, 100);

// Set pagination variables
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$limit = 10;
$totalItems = count($data);
$totalPages = ceil($totalItems / $limit);
$page = max($page, 1);
$page = min($page, $totalPages);
$offset = ($page - 1) * $limit;

// Get the data for the current page
$currentPageData = array_slice($data, $offset, $limit);

// Display the paginated data
foreach ($currentPageData as $item) {
    echo $item . "<br>";
}

// Display pagination links
for ($i = 1; $i <= $totalPages; $i++) {
    echo '<a href="?page=' . $i . '">' . $i . '</a> ';
}
