Witam serdecznie,
Mam taką tablicę:

Muszę przesortować te wartości po 5,4,3 i 2 ostatnich polach (czyli od końca odliczając po "|"). Wiecie może jak to zrobić?
Próbuję z tym już od 2 dni, ale już nie mam pomysłów (IMG:style_emoticons/default/sad.gif)

niestety nie pomogło:(

znalazłem taki kod:

[PHP] pobierz, plaintext 

ten kod z multisort działa extra dla nazwy...

tylko w przypadku gdy mam:
$t1[$key] = $row[11];
array_multisort($t1, SORT_ASC, $tablica_sortowania);

to sortuje jakoś dziwnie: 1.30 , 2.40, 1.60, 1.80, 2.40, 2.00

Wiecie może dlaczego tak jest? dlaczego nie sortuje poprawnie?
