This function will send the contents of the output buffer (if any). If you
want to further process the buffer's contents you have to call
<span class="function"><a href="function.ob-get-contents.html" class="function">ob_get_contents()</a></span> before <span class="function"><strong>ob_flush()</strong></span>
as the buffer contents are discarded after <span class="function"><strong>ob_flush()</strong></span>
is called.

This function does not destroy the output buffer like
<span class="function"><a href="function.ob-end-flush.html" class="function">ob_end_flush()</a></span> does.
