How can PHP beginners effectively troubleshoot pagination issues in custom forum portals built around existing forum software like SMF?

To troubleshoot pagination issues in custom forum portals built around existing forum software like SMF, PHP beginners can start by checking the pagination logic in the code to ensure it is correctly implemented. They should also verify that the database query fetching the forum posts is returning the correct number of results based on the pagination parameters. Additionally, they can debug any errors or warnings related to the pagination functionality to identify and fix any issues. 

// Example code snippet to troubleshoot pagination issues in a custom forum portal

// Check pagination parameters
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$posts_per_page = 10;
$offset = ($page - 1) * $posts_per_page;

// Fetch forum posts from database
$query = "SELECT * FROM forum_posts LIMIT $offset, $posts_per_page";
$result = mysqli_query($connection, $query);

// Display forum posts
while($row = mysqli_fetch_assoc($result)) {
    echo $row['post_content'];
}

// Display pagination links
$total_posts = mysqli_num_rows(mysqli_query($connection, "SELECT * FROM forum_posts"));
$total_pages = ceil($total_posts / $posts_per_page);

for($i = 1; $i <= $total_pages; $i++) {
    echo "<a href='forum.php?page=$i'>$i</a>";
}
