[PHP] Da sie z tego petle zrobic? Opcje

[Bojakki]

Mam taki kod:

[PHP] pobierz, plaintext 
<?php
switch ($genre_id)
{
    case 1: $genre_name=$f1; break;
    case 2: $genre_name=$f2; break;
    case 3: $genre_name=$f3; break;
    case 4: $genre_name=$f4; break;
    case 5: $genre_name=$f5; break;
    case 6: $genre_name=$f6; break;
    case 7: $genre_name=$f7; break;
    case 8: $genre_name=$f8; break;
    case 9: $genre_name=$f9; break;
    case 10: $genre_name=$f10; break;
    case 11: $genre_name=$f11; break;
    case 12: $genre_name=$f12; break;
    case 13: $genre_name=$f13; break;
    case 14: $genre_name=$f14; break;
    case 15: $genre_name=$f15; break;
}
?>

Zmienne zmienne:

[PHP] pobierz, plaintext 
<?php
if($genre_id >= 1 && $genre_id <=150) $genre_name = ${'f'.$genre_id};
?>

[PHP] pobierz, plaintext 
<?php
$genre_id = 1;
 
$f1 = 'lalala';
$f2 = 'nanana';
 
$genre_name = ${'f'.$genre_id};
 
echo $genre_name;
?>
[PHP] pobierz, plaintext 

Ja bym jednak sugerował zapis w formie tablicy ($f[1], $f[2]) zamiast $f1, $f2.
