In the above example, the output from <span class="function"><a href="function.echo.html" class="function">echo</a></span>
would be stored in the output buffer until
<span class="function"><a href="function.ob-end-flush.html" class="function">ob_end_flush()</a></span> was called. In the mean time,
the call to <span class="function"><a href="function.setcookie.html" class="function">setcookie()</a></span> successfully stored a
cookie without causing an error. (Headers cannot normally be sent
to the browser after data has already been sent.)
