With cleaner I mean I won't have several (around 15 for now. This will
increase) lines where I might need to edit $File to $FILE or whatever if
I change some code. For sure I will forget at least one line somewhere.

I do not need it here. I could as easily use:
function write_fifo($data) {
$File = "test.txt";
echo $data."<br>".$File."<hr>";
$fh = fopen($File, 'w') or exit("can't open file -".$File."= .");
fwrite($fh, $data);
fclose($fh);
}
write_fifo("Something Here");

Or write it in full and not use a parameter at all for $File.

write_fifo("Something Here"); is much more logical then
write_fifo("Something Here";"some_file"); as it involves an action,
rather then just writing to a file. The real name will not be
write_fifo, but rather mplayer

It will steer mplayer that is running in slave mode. e.g. one will be:
Some of them:
mplayer("pause"); // Pause/Play
mplayer("quit"); // Quit
mplayer("volume -10"); // Louder
mplayer("volume +10"); // Softer
mplayer("loadfile $film 0"); // Start playing a movie

So the $File part is not something I would like to have there as it does
not make thing more clear, but instead will make it less clear what is
going on or what the code is supposed to do at that point.
