PHP fails to parse large post variable

Question

I'm trying to pass a rather large post request to php, and when I var_dump $_POST array, one, the most large, variable is missing. (Actually that's base64 encoded binary upload as part of a post request)

Funny thing, that on my development PC exactly same request is parsed correctly, without any missing variables.

I checked out contents of php://input on server and development PC and they are exactly the same, md5 matches. Yet development PC recognizes all variables, and server misses one. I tried changing many different options in php.ini, and got zero effect.

Maybe someone will point me to the right one. Here is my php://input (~5 megabytes) http://www.mediafire.com/?lp0uox53vhr35df

Your probably hitting the max_post_size that's been set in the .ini — BenOfTheNorth, Feb 20 '12 at 18:19
Nope, it's already 220M. And if that would be it, php://input would not contain entire information. — Nameless, Feb 20 '12 at 18:24
I'd expect the memory limit being ok - but have you checked to make sure it's set high enough to also process the size? I'd be surprised if it wasn't though. — BenOfTheNorth, Feb 20 '12 at 18:31
128M should be pretty okay for the task of parsing 5 mb input, right? I can double-check value in runtime, or increase it to test things. — Nameless, Feb 20 '12 at 18:33
Having the limit at 128mb will limit the max post to 128mb, but it should of course be plenty to handle a 5mb post. — BenOfTheNorth, Feb 20 '12 at 18:36

It's possible the server is blocking it because of Suhosin extension.

http://www.hardened-php.net/suhosin/configuration.html#suhosin.post.max_value_length

suhosin.post.max_value_length

Type: Integer Default: 65000 Defines the maximum length of a variable that is registered through a POST request.

This will have to be changed in the php.ini.

Keep in mind that this is different than the Suhosin patch which is common on alot of shared hosts. I don't know if the patch would cause this problem.

suhosin.post.max_value_length = 250000000 Unfortuantely I have already tried that. Maybe format is not right, I'll check this value in runtime about 7 hours later. – Nameless Feb 21 '12 at 08:43
It worked together with suhosin.request.max_value_length. I will mark your answer as correct, it was the closest one. – Nameless Feb 21 '12 at 17:14
