How can PHP developers prevent the incorrect transfer of "&" in form submissions?

To prevent the incorrect transfer of "&" in form submissions, PHP developers can use the urlencode() function to encode the data before sending it and then use urldecode() function to decode it when processing the form submission. 

// Encoding the form data before sending
$data = urlencode($_POST['data']);

// Decoding the form data when processing the submission
$decoded_data = urldecode($data);
