<simpara>
|
|
Flushes the output buffers of PHP and whatever backend PHP is
|
|
using (CGI, a web server, etc). This effectively tries to push
|
|
all the output so far to the user's browser.
|
|
</simpara>
|
|
<para>
|
|
<function>flush</function> has no effect on the buffering
|
|
scheme of your webserver or the browser on the client
|
|
side.
|
|
</para>
|
|
<para>
|
|
Several servers, especially on Win32, will still buffer
|
|
the output from your script until it terminates before
|
|
transmitting the results to the browser.
|
|
</para>
|
|
<para>
|
|
Server modules for Apache like mod_gzip may do buffering of their own
|
|
that will cause <function>flush</function> to not result in data being
|
|
sent immediately to the client.
|
|
</para>
|
|
<para>
|
|
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.
|
|
</para>
|
|
<para>
|
|
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.
