What are some strategies for debugging PHP scripts that interact with databases, especially when dealing with browser memory limitations?

When debugging PHP scripts that interact with databases and facing browser memory limitations, one strategy is to limit the amount of data being fetched from the database at once by using pagination. This helps reduce the memory usage and improves the performance of the script. 

// Example of implementing pagination in PHP when fetching data from a database

// Set the limit of results per page
$limit = 10;

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

// Calculate the offset for the SQL query
$offset = ($page - 1) * $limit;

// Query the database with the limit and offset
$sql = "SELECT * FROM table_name LIMIT $limit OFFSET $offset";
$result = mysqli_query($connection, $sql);

// Loop through the results and display them
while($row = mysqli_fetch_assoc($result)) {
    // Display the data
}

// Add pagination links for navigating between pages
$total_pages = ceil($total_results / $limit);
for($i = 1; $i <= $total_pages; $i++) {
    echo "<a href='?page=$i'>$i</a> ";
}
