What are the best practices for handling large amounts of data from input forms in PHP to avoid excessive data retrieval efforts?

When handling large amounts of data from input forms in PHP, it is important to avoid excessive data retrieval efforts by properly sanitizing and validating the input data. One way to do this is by using PHP's filter_input_array function to retrieve and filter input data from multiple form fields efficiently. This function allows you to specify an array of input fields and their corresponding filter types, making it easier to handle large amounts of data securely. 

$input_data = filter_input_array(INPUT_POST, [
    'field1' => FILTER_SANITIZE_STRING,
    'field2' => FILTER_SANITIZE_EMAIL,
    // Add more fields as needed
]);

// Access sanitized input data
$field1 = $input_data['field1'];
$field2 = $input_data['field2'];
