flush
(PHP 4, PHP 5)
flush — Flush the output buffer
Description
void flush
( void
)
flush() has no effect on the buffering scheme of your
web server or the browser on the client side.
Thus you need to call both ob_flush() and
flush() to flush the output buffers.
Several servers, especially on Win32, will still buffer the output from
your script until it terminates before transmitting the results to the
browser.
Server modules for Apache like mod_gzip may do buffering of their own that
will cause flush() to not result in data being sent
immediately to the client.
Even the browser may buffer its input before displaying it. Netscape, for
example, buffers text until it receives an end-of-line or the beginning of
a tag, and it won't render tables until the </table> tag of the
outermost table is seen.
Some versions of Microsoft Internet Explorer will only start to display
the page after they have received 256 bytes of output, so you may need to
send extra whitespace before flushing to get those browsers to display the
page.
Return Values
