foreach 输出显示、进度问题,求助高手解决。

$citycode = array("北京"=>"101010100",
"青县"=>"101090702",
"磁县"=>"101091007",
"嘉义"=>"101340901",
"阿里山"=>"101340902",
"玉山"=>"101340903",
"新港"=>"101340904"
);
foreach ($citycode as $key=>$value ) {

echo '输出'.$value.'
';

}
?>


我要输出数组,但数组可能非常多(我要用数组做些生成的工作),我想数组一条一条,或者5条5条慢慢显示。因为不这样的话,我要等很久才看到执行结果,看不到执行进度。
------解决思路----------------------
在最前面加上下面语句
ob_start(); //打开输出缓冲区
ob_end_flush();
ob_implicit_flush(1); //立即输出
可以立即输出你的输出内容
