flush()函数无效？不能实时刷新输出，怎么解决呢

flush()函数无效？不能实时刷新输出，如何解决呢？

本帖最后由 zhoumengkang 于 2013-05-28 13:46:14 编辑 测试代码如下：

<?php<br />
for($i=0;$i<5;$i++){  <br />
	echo '<br/>abc___'.$i;<br />
	ob_flush();<br />
	flush();<br />
	sleep(1);<br />
}<br />
ob_end_flush();<br />
?> 

理论上应该是1秒出来一条是吧？但是我测试的结果是5秒之后才一起出来。
网上查了下有这样说的“个别web服务器程序，特别是Win32下的web服务器程序，在发送结果到浏览器之前，仍然会缓存脚本的输出，直到程序结束为止。 ”我这个是64位的windows的本地xampp的集成环境。

------解决方案--------------------
我又回来了，试试

<?php<br />
echo str_pad('',4096);<br />
<br />
set_time_limit(50);<br />
for($i=0;$i<=5;$i++){<br />
    echo $i.'<br />';<br />
ob_flush();<br />
flush(); <br />
sleep(1);<br />
}<br />
?>

这两天出这个问题的还挺多的。
这个写法在各浏览器测试都没问题，但有童鞋说，这种做法往缓存区写垃圾，可以试试PHP抛出异常，有空研究一下再分享。
