What are some best practices for implementing page navigation in PHP?

When implementing page navigation in PHP, it is important to consider factors such as the total number of items to display per page, the current page number, and the total number of pages. One common approach is to use URL parameters to pass the current page number between pages. By keeping track of the current page number and adjusting the displayed content accordingly, users can easily navigate through different pages of content. 

// Example implementation of page navigation in PHP

// Define total number of items and items per page
$totalItems = 100;
$itemsPerPage = 10;

// Get current page number from URL parameter
$page = isset($_GET['page']) ? $_GET['page'] : 1;

// Calculate total number of pages
$totalPages = ceil($totalItems / $itemsPerPage);

// Display items for current page
$start = ($page - 1) * $itemsPerPage;
$end = $start + $itemsPerPage;
for ($i = $start; $i < $end; $i++) {
    echo "Item " . ($i + 1) . "<br>";
}

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