File size limitations on POST upload?

TalonFinsky

I've got a weird one for you folks, if you don't mind helping out.

I'm currently working on a project which, among other things, allows users to upload large text files to be processed. These files can (and will) exceed 10MB, so it's dealing with some pretty hefty files.

The problem I'm running into is a strange one. On one server (let's call it server "A"), if the file you're uploading is greater than, say, 400K it'll give you an error (Page cannot be displayed in IE, Document contains no data in Firefox).

I took the code, moved it over to a different server (let's call it server 😎, and all works well - I can upload any size file I want.

I looked over the php.inis between the two, and they're identical. The "post_max_size" is the same on both, along with file_uploads, upload_max_filesize, and upload_tmp_dir.

What's really killing me is that this script was running just fine previously. I'm not sure at all what changes there have been that could have affected this.

Any ideas? Both servers are running Apache2, but Server A is running PHP 4.2.2, while Server B is running PHP 5.0.2.

Thanks,

Well id say there be a slightly different configuration between the two. I cannot say for sure however I dont think there is much difference between PHP 4 and PHP 5 with how they handle file uploads.

Yeah, there's obviously something different between the two, but I just can't figure out what the heck it could be.

Well I cannot say for sure what it is exactly without probably looking at a few things unfotunately most of us here arent mind readers and know everyones php.ini configurations.

It could have something to do with post_max_size (i think it is) which is included within a form uploading a file, I dont think PHP 5 trusts this and ignores it however PHP 4 uses it in most environments. It could be the Server and not a PHP Configuration which allows that however you would more than likely notice this when using FTP.

How about max_input_time & max_execution_time ??

max input time and execute time dont work on file uploads. Bascily from the 2nd you sumit your form it starts a fileupload. IT wont start processing the destiantion page and the new max ececute time code till after the file is done. And if it has taken longer than what is set in the php.ini file it will thena bort. I have had this happen alot because of dailup users and bad connections. You need to do an iniset though i think you cant change that particular setting via iniset but it can be set in a .htacccess file i think or just changed in the actualy ini file. Also some other thigns to look at are the directory permissions on both servers. this also includes the tmp dir and destinations and wether the HTTP server user can actually access them.
