Opis

public string streamWrapper::stream_read ( int $count )

Parametry

count

How many bytes of data from the current position should be returned.

Zwracane wartości

If there are less than count bytes available, return as many as are available. If no more data is available, return either FALSE or an empty string.

Błędy/Wyjątki

Zgłasza E_WARNING jeśli wywołanie tej metody nie powiedzie się (np. nie jest zaimplementowana).

Informacja: If the return value is longer then count an E_WARNING error will be emitted, and excess data will be lost.

Notatki

Informacja: streamWrapper::stream_eof is called directly after calling streamWrapper::stream_read to check if EOF has been reached. If not implemented, EOF is assumed.
