When manipulating form data in PHP, it is recommended to use array functions like array_filter or array_intersect_key to efficiently filter or extract specific elements from an array. These functions can help simplify the code and make it easier to work with form data by only selecting the necessary elements. 

// Example of using array_filter to remove empty values from form data
$formData = $_POST;
$cleanedData = array_filter($formData);

// Example of using array_intersect_key to extract specific keys from form data
$allowedKeys = ['name', 'email', 'message'];
$filteredData = array_intersect_key($formData, array_flip($allowedKeys));
