for ($i=0; $i ob_start();
echo "This is iteration $i: ";
// * Dont do this!
// $buf = ob_get_contents();
// ob_clean();
// * Use this instead:
$buf = ob_get_flush();
//缓冲区关闭，竟然还有内容
$test=ob_get_contents();
echo $test,---->;
echo $buf;
echo memory_get_usage()." ";

ob_get_flush相当于ob_end_flush,只有一点区别，ob_get_flush获取缓存区内容，保存到变量中，并关闭缓存区。
