php在大文件上传时丢失表单字段

Question

so i've read that php clears the $_POST variable when an upload or other data exceeds the limits on POST data. Thus if the user uploads a really big file which php/apache rejects, their form fields will get cleared out and you wont be able to repopulate them. is there a way to get around this? Is this a php issue or an apache issue?

Answer 1

is there a way to get around this?

Many ways, one of them is just to give a 500 response and dying straight away.

Is this a php issue or an apache issue?

Can be both, but I assume it's just that you're hitting the PHP limit for post max size or the memory limit. Configure your server that you have enough resources to handle the file uploads you wish.
