Mam problem z przekierowaniem.
Cały skrypt się wykonuje ale po wykonaniu nie przekierowuje do danego pliku (rps.php).

Skrypt:

Jaki komunikat dostajesz? Jeśli coś w rodzaju 'Headers already sent' daj tuż po <?php

[PHP] pobierz, plaintext 
ob_start();
[PHP] pobierz, plaintext 

a tuż przed ?>

[PHP] pobierz, plaintext 
ob_get_clean();
[PHP] pobierz, plaintext 

Problem był właśnie w tym, że nie otrzymywałem komunikatu.
Ale twoja metoda pomogła, dzięki
