http_throttle -- HTTP throttling

Description

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

Sets the throttle delay and send buffer size.

Note: This function is supposed to be used in conjunction with http_send_data(), http_send_file() and http_send_stream().

Note: Provides a basic throttling mechanism, which will yield the current process respectively thread until the entity has been completely sent.

Note: This may not work as expected with the following SAPI(s): FastCGI.

Example 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);
http_send_file('document.pdf');
?>
