Flushes the system write buffers of PHP and the backend used by PHP
|
|
(e.g.: CGI, a web server).
|
|
In a command line environment <function>flush</function>
|
|
will attempt to flush the contents of the buffers only
|
|
whereas in a web context headers and the contents of the buffers are flushed.
|
|
</para>
|
|
<note>
|
|
<simpara>
|
|
<function>flush</function> may not be able to override
|
|
the buffering scheme of the web server
|
|
and it has no effect on any client-side buffering in the browser.

<note>

<simpara>
|
|
This function does not have any effect on user level output handlers
|
|
such as those started by <function>ob_start</function>
|
|
or <function>output_add_rewrite_var</function>.
|
|
</simpara>
|

</note>
|
|
<warning>
|
|
<simpara>
|
|
<function>flush</function> can interfere with output handlers
|
|
that set and send headers in a web context (e.g. <function>ob_gzhandler</function>)
|
|
by sending headers before these handlers can do so.
