此函数丢弃最顶层输出缓冲区的内容并关闭这个缓冲区。如果想要进一步处理缓冲区的内容，必须在<span class="function"><strong>ob_end_clean()</strong></span>之前调用<span class="function"><a href="ob_get_contents.html" class="function">ob_get_contents()</a></span>，因为当调用<span class="function"><strong>ob_end_clean()</strong></span>时缓冲区内容将被丢弃。

成功时返回 <strong><code>TRUE</code></strong>， 或者在失败时返回 <strong><code>FALSE</code></strong>。 错误的原因首先是，在调用时没有一个起作用的缓冲区，或者是因为某些原因缓冲区不能被删除（可能对特殊缓冲区而言）。
