How to send bare text if empty (php)?

Question

PHP

if(empty($getdata[$name]['value'])) {
                     unset($getdata[$name]);
                  }

There is a piece of code that says - "if the field in the form is not filled, then cancel the transfer of its data." How to write in php instead of unset($getdata[$name]); so that the text "not filled" was stupid ?
Tried echo "..."; and print "...."; does not fuss, nothing comes from this field in the letter at all. What's the matter huh

Answer 1

I finished it myself (I don’t know how crooked it is, but it seems to be nothing like this):

if(empty($getdata[$name]['value'])) {
$emptyField = 'не заполнено';
$getdata[$name]['value'] = htmlspecialchars($emptyField);
}

Answer 2

Seems

if($getdata[$name]['value']<>''){
echo "Не заполнено";
}

Answer 3

if(empty($getdata[$name]['value'])) {
unset($getdata[$name]);
echo 'не заполнено';
}

if(empty($getdata[$name]['value'])) {
unset($getdata[$name]);
$message = 'не заполнено';
return $message;
}
