http_throttleHTTP throttling

Описание

void http_throttle ([ float $sec [, int $bytes = 40960 ]] )

Sets the throttle delay and send buffer size.

Забележка: Тази функция би трябвало да се използва в комбинация с http_send_data(), http_send_file() и http_send_stream().

Забележка: Предоставя основен потискащ механизъм, който ще отстъпи предимството на текущия процес или нишка докато съответният обект не се изпрати напълно.

Забележка: Възможно е това да не работи според очакваното със следните SAPI(та): FastCGI.

Параметри

Note that in the example when it says "Send file with approximately 20 kbyte/s." that is only an upper bound. The file could still be sent at a lesser speed (e.g. 10 kb/s) if the client, network, or server, cannot handle the amount.
