What are the potential challenges in using AJAX or JavaScript for Excel-like functionality in PHP?

One potential challenge in using AJAX or JavaScript for Excel-like functionality in PHP is handling large amounts of data efficiently. To solve this, you can implement pagination or lazy loading to only load and display a portion of the data at a time, reducing the strain on the server and improving performance. 

// Example PHP code implementing pagination for handling large amounts of data
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$limit = 10;
$offset = ($page - 1) * $limit;

// Query to retrieve data from database with pagination
$query = "SELECT * FROM table_name LIMIT $offset, $limit";
$result = mysqli_query($connection, $query);

// Display data in HTML table
echo "<table>";
while($row = mysqli_fetch_assoc($result)) {
    echo "<tr><td>".$row['column1']."</td><td>".$row['column2']."</td></tr>";
}
echo "</table>";

// Pagination links
$total_pages = ceil($total_records / $limit);
for ($i=1; $i<=$total_pages; $i++) {
    echo "<a href='?page=".$i."'>".$i."</a> ";
}
