What are some common pitfalls when trying to display a specific number of entries per page in PHP?

One common pitfall when trying to display a specific number of entries per page in PHP is not properly handling pagination. To solve this issue, you need to calculate the total number of entries, determine the current page number, and then display the appropriate subset of entries based on the desired number of entries per page.

// Assuming $entries is an array of all entries and $entriesPerPage is the desired number of entries per page
$totalEntries = count($entries);
$currentPage = isset($_GET['page']) ? $_GET['page'] : 1;
$start = ($currentPage - 1) * $entriesPerPage;
$end = $start + $entriesPerPage;

// Display entries for the current page
for ($i = $start; $i < min($end, $totalEntries); $i++) {
    echo $entries[$i];
}

// Pagination links
$totalPages = ceil($totalEntries / $entriesPerPage);
for ($i = 1; $i <= $totalPages; $i++) {
    echo "<a href='?page=$i'>$i</a> ";
}
