What are the potential pitfalls of not using the LIMIT parameter in a SQL query for pagination in PHP?

When not using the LIMIT parameter in a SQL query for pagination in PHP, the database will return all matching records, which can lead to performance issues and slow page load times, especially when dealing with large datasets. To avoid this, it is important to include the LIMIT parameter in the SQL query to limit the number of records returned per page. 

// Example PHP code snippet with LIMIT parameter for pagination
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$records_per_page = 10;
$offset = ($page - 1) * $records_per_page;

$sql = "SELECT * FROM table_name LIMIT $offset, $records_per_page";
// Execute the SQL query and fetch results
