What are the potential pitfalls of retrieving extensive descriptions from a database in PHP?

Retrieving extensive descriptions from a database in PHP can lead to performance issues due to the large amount of data being transferred and processed. To solve this problem, you can limit the amount of data retrieved by using pagination or by fetching only the necessary information. 

// Example of limiting the amount of data retrieved using pagination
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$limit = 10;
$offset = ($page - 1) * $limit;

$query = "SELECT * FROM table LIMIT $offset, $limit";
$result = mysqli_query($conn, $query);

while($row = mysqli_fetch_assoc($result)) {
    // Process and display data
}
