php的include和ob函数在循环中导致的

程序大概如下
...
foreach($arr as $value){
  ob_start();
  include template($value['filename']);
  $message = addslashes(trim(ob_get_contents()));
  ob_end_clean();
}

这种模式执行5000条数据 就会出现

Too many open files的错误 

如果执行数为1000没有问题

怎么解决啊

------解决方案--------------------
Too many open files 是打开文件太多
你应考虑换个思路,而不是 include
------解决方案--------------------
建议你查一下ob_start和ob_end_clean()、ob_get_contents()的用法,理解清楚了就知道怎么回事了
PHP code

ob_start();
foreach($arr as $value){
  include template($value['filename']);
  $message = addslashes(trim(ob_get_contents()));
  ob_end_clean();
};

------解决方案--------------------
foreach($arr as $value){
ob_start();
include template($value['filename']);
$message = addslashes(trim(ob_get_contents()));
ob_end_clean();
}

话说你这样是生成静态吗?

用请求跳转来分批做啊

伪代码演示

触发请求:dosomeing.php?page=1&per=1000;

PHP code
$arr = $data.limit((page-1)*$per, per)

foreach($arr as $value){
  ob_start();
  include template($value['filename']);
  $message = addslashes(trim(ob_get_contents()));
  ob_end_clean();
}
$page++;
header('Location: dosomeing.php?page='.$page.'&per='.$per)

------解决方案--------------------
php 版本? 5.2.6? 
可能是php的bug

试试把include改为include_once
