HTTP_THROTTLE(3) 1 HTTP_THROTTLE(3) http_throttle - HTTP throttling SYNOPSIS
void http_throttle (float $sec, [int $bytes = 40960]) DESCRIPTION
Sets the throttle delay and send buffer size. Note This function should be used in conjunction with http_send_data(3), http_send_file(3) and http_send_stream(3). 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
o $sec - seconds to sleep after each chunk sent o $bytes - the chunk size in bytes EXAMPLES
Example #1 A http_throttle(3) 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'); ?> SEE ALSO
http_send_data(3), http_send_file(3), http_send_stream(3), the HttpResponse class if you are using PHP 5.1.0 and above. PHP Documentation Group HTTP_THROTTLE(3)
