Description

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

Sets the throttle delay and send buffer size.

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

# http_throttle(0.5, 10000);
http_throttle(0.12000);
