What are best practices for handling large amounts of data in HTML forms in PHP?

When handling large amounts of data in HTML forms in PHP, it is important to use POST method instead of GET to avoid data size limitations. Additionally, you can increase the PHP settings for max_input_vars and post_max_size to accommodate larger amounts of data. It is also recommended to validate and sanitize the input data to prevent security vulnerabilities.

php 
// Increase max_input_vars and post_max_size in php.ini
ini_set('max_input_vars', 3000);
ini_set('post_max_size', '20M');

// Validate and sanitize input data
$input_data = $_POST['input_data'];
$validated_data = filter_var($input_data, FILTER_SANITIZE_STRING);

// Process the validated data
// ...
