关于apache2.x+php5.2x的大文件上传内存占用

求教一个问题，网上有资料说php上传大文件，文件会一直被缓存在内存里，不像asp.net会有一个阙值，超过的话就会写在磁盘上。

但我在实际操作时，用swfupload或是传统上传，都没有发现机器的内存出现明显的上升
是不是php5做了这块的改进？还是什么原因？
真心求教

回复讨论(解决方案)

我晕，这是怎么了，

move_uploaded_file( $file['tmp_name'], $new_file )
将上传到服务器的临时文件命名到指定的目录下。

那是已经生成临时文件之后的事情了。。。
这个临时文件生成的时候，是先放在内存里，然后一次性写入的，还是分段写入的，我不太知道。

说白了，就是上传1g的文件，会不会占用1g的内存？

从我这里测试的情况来看，是不会占用这么大，但是之前网上的文章又说会的，所以为了确保这个信息的准确性，还是来问一下

你可以上传大的文件，通过任务管理器，看下内存变化（比如导入文件）。

坦白来说，没有找到满意答案，你提供的方案，我在发贴时就已经试过了
但我个人资源有限，并没有办法把测试覆盖任一版本的任一平台。
这种测试是不严谨的
