http_throttle — HTTP throttling
Description
void http_throttle
([ float $sec
[, int $bytes = 40960
]] )
Sets the throttle delay and send buffer size.
Note: This function should 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 or thread until the entity has been completely sent.
Note:
This may not work as expected with the following SAPI(s): FastCGI.
Parameters
- sec
-
seconds to sleep after each chunk sent
- bytes
-
the chunk size in bytes
Examples
Example #1 A http_throttle() example

<?php
// ~ 20 kbyte/s
# http_throttle(1, 20000);
# http_throttle(0.5, 10000);
http_throttle(0.1, 2000);
http_send_file('document.pdf');
?>
