What are some common challenges when displaying tabular data in PHP, especially when retrieving data from a MySQL database?

Common challenges when displaying tabular data in PHP, especially when retrieving data from a MySQL database, include handling pagination, sorting, and filtering of the data. To solve these challenges, you can use SQL queries with LIMIT and OFFSET clauses for pagination, ORDER BY clause for sorting, and WHERE clause for filtering. 

// Example code for handling pagination, sorting, and filtering of tabular data in PHP

// Retrieve data from MySQL database with pagination
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$limit = 10;
$offset = ($page - 1) * $limit;

$sql = "SELECT * FROM table_name LIMIT $limit OFFSET $offset";
$result = mysqli_query($conn, $sql);

// Sorting data
$sort = isset($_GET['sort']) ? $_GET['sort'] : 'id';
$order = isset($_GET['order']) ? $_GET['order'] : 'ASC';

$sql = "SELECT * FROM table_name ORDER BY $sort $order";
$result = mysqli_query($conn, $sql);

// Filtering data
$filter = isset($_GET['filter']) ? $_GET['filter'] : '';
$sql = "SELECT * FROM table_name WHERE column_name LIKE '%$filter%'";
$result = mysqli_query($conn, $sql);
