How can debugging techniques, such as var_dump and print_r, be effectively utilized to troubleshoot pagination issues in PHP scripts, as suggested in the forum responses?

Pagination issues in PHP scripts can be effectively troubleshooted using debugging techniques like var_dump and print_r to inspect the variables and arrays involved in the pagination process. By examining the values of variables such as the current page number, total number of items, and items per page, developers can identify any discrepancies or errors causing the pagination to malfunction.

// Example of how var_dump can be used to troubleshoot pagination issues

// Assuming $currentPage, $totalItems, and $itemsPerPage are the variables involved in pagination

var_dump($currentPage);
var_dump($totalItems);
var_dump($itemsPerPage);

// Check if the values of $currentPage, $totalItems, and $itemsPerPage are as expected
// Make necessary adjustments to ensure correct pagination logic
