  <para>
   <function>ob_implicit_flush</function> 将打开或关闭绝对（隐式）刷送。绝对（隐式）刷送将在每个代码块产生输出后执行刷新操作，以便不再手动调用 <function>flush</function>。
  </para>
  <note>
   <simpara>
    打印空字符串或发送 header 不会视为输出，因此不会产生刷新操作。

  <note>
   <simpara>
    此函数对用户级输出处理程序（例如由 <function>ob_start</function> 或 <function>output_add_rewrite_var</function> 启动的处理程序）没有任何影响。
