Problem with get_field() and passing parameters

Hello people,

So, I have a weird problem with get_field() function.

Here is my problem:
I’ve created a class with a function that will pass my parameters for checking if is some field empty or not.

I’ve many declared variables, so I don’t want to repeat code again and again.

For example: In file1.php I have this class:

class wow {
    public $emptyString = '';
    public $data;

    function emptyValue($emptyString, $data) {
        $empty = empty($data) ? $emptyString : $data;
        echo $empty;
    }
}
$wow = new wow();

And in file2.php I call the function:

include 'file1.php';
$header_first_icon_title = get_field ('header_first_icon_title');

$wow->emptyValue('Field is empty', $header_first_icon_title );

This only works when I declare $header_first_icon_title = get_field ('header_first_icon_title'); right to the $wow->emptyValue('Field is empty', $header_first_icon_title ); Literally in one line above.

If I declare $header_first_icon_title = get_field ('header_first_icon_title'); on the top of the file, and I call $wow->emptyValue('Field is empty', $header_first_icon_title ); for example after 2, 3 houndres of html lines this will not catch the $data. It will only return "Field is empty".

Also, for example, if I do something like this:
$wow->emptyValue('Field is empty', get_field ('header_first_icon_title')); everything working.

I’m not sure why this happens. I don’t get any errors. I want to declare all variables on the top, so I can call them where I need them later in the file.

If someone can help me/explain to me why this has this behavior I would be more then thankful.
