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.

http_throttle — HTTP throttling
$sec
[, int $bytes
= 40960
] )Sets the throttle delay and send buffer size.
Nota: Esta função deve ser utilizada em conjundo com http_send_data(), http_send_file() e http_send_stream().
Nota: Fornece mecanismo básico de moderação (throttling), que suspende o processo atual ou thread até que o dado tenha sido completamente enviado.

Isto não funciona como esperado na(s) seguinte(s) SAPI(s): FastCGI.

seconds to sleep after each chunk sent
bytes
the chunk size in bytes
Exemplo #1 A http_throttle() example
Send file with approximately 20 kbyte/s.
<?php
// ~ 20 kbyte/s
# http_throttle(1, 20000);
# http_throttle(0.5, 10000);
http_throttle(0.1, 2000);
