How can debugging techniques be applied to identify and resolve issues with PHP pagination?

Issue: When implementing PHP pagination, some common issues that may arise include incorrect page numbers, missing results, or broken links. To identify and resolve these issues, debugging techniques such as printing out variables, checking query results, and verifying pagination logic can be applied. Code snippet: 

// Assuming $total_pages contains the total number of pages and $current_page contains the current page number

// Debugging technique: Print out variables to check values
echo "Total Pages: " . $total_pages . "<br>";
echo "Current Page: " . $current_page . "<br>";

// Debugging technique: Check query results
// Make sure your query fetches the correct results for the current page
// Adjust your query to fetch the correct results based on the current page number

// Debugging technique: Verify pagination logic
// Make sure your pagination logic is correctly calculating the start and end limits for displaying results
$start_limit = ($current_page - 1) * $results_per_page;
$end_limit = $start_limit + $results_per_page;

// Use $start_limit and $end_limit in your query to fetch results for the current page
$query = "SELECT * FROM table_name LIMIT $start_limit, $end_limit";
// Execute the query and display results
