您可以为post_max_size或upload_max_filesize设置的值有任何限制吗？

Question

I am tasked with creating an uploader for a site that can handle very large files to avoid the clients having to use ftp as the means to send. By very large I mean upwards to 2 gigs in size. I have researched a few options and tested a couple implementations, one of them is:

Only problem is this one does no file chunking ( that I know of ) so it requires me setting post_max_size and upload_max_filesize to ridiculous numbers to compensate. Is there a limit to what you can set this up to? Big reasons against doing so?

Thanks in advance.

Answer 1

PHP's pretty crappy when it comes to large file uploads, particularly because you have to a memory limit higher than the size of the file. As well, Apache on 32bit systems tends to have a 2gig file limit itself, so even if PHP could handle the upload, Apache will choke.
