这个函数将送出最顶层缓冲区的内容（如果里边有内容的话），并关闭缓冲区。如果想进一步处理缓冲区中的内容，必须在<span class="function"><strong>ob_end_flush()</strong></span>之前调用
|
||
<span class="function"><a href="ob_get_contents.html" class="function">ob_get_contents()</a></span>，因为在调用<span class="function"><strong>ob_end_flush()</strong></span>后缓冲区内容被丢弃。

这个函数与<span class="function"><a href="ob_get_flush.html" class="function">ob_get_flush()</a></span>相似，不同的是<span class="function"><a href="ob_get_flush.html" class="function">ob_get_flush()</a></span>会把缓冲区中的内容作为字符串返回。

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）。
