Are there any potential pitfalls to be aware of when deleting values from the $_POST array in PHP?

When deleting values from the $_POST array in PHP, be aware that it can potentially lead to unexpected behavior in your application. It is recommended to create a copy of the $_POST array and modify the copy instead of directly altering the original array. This way, you can avoid unintentionally removing important data that may be needed later in the script. 

// Create a copy of the $_POST array
$post_copy = $_POST;

// Unset specific values from the copy
unset($post_copy['key_to_delete']);
