Dlaczego ten kod mi nic nie zwraca?

sprawdź w error log i zdefiniuj nic nie zwraca

A gdzie mam ten errorlog? Debian 7 64 bit

prawdopodobnie:
/var/log/php_errors.log
/var/log/apache2/error.log

albo w innym katalogu zgodnie z Twoja konfiguracją

Błąd po włączeniu flag błędów
Notice: Undefined index: send_ftp in /home/admin/web/xxxx.pl/public_html/test.php on line 6
Po naciśnięciu dodaj:
Fatal error: Call to undefined function ssh2_connect() in /home/admin/web/xxxx.pl/public_html/test.php on line 10

W pierwszym błędzie dałem $_POST w isset, a w drugim musiałem zainstalować liby

Proszę nadać tematowi sensowny tytuł. W przeciwnym razie zostanie zamknięty.

// Edit:

Prośba zignorowana więc wątek zamykam.
