Description:
------------
Please see my last note to bug #22427.  I am experiencing the same problem, I would not submit this again, except, it appears that I can not change the status to open again, since I am not the owner, so I added this to one to point to that.

Yup, confirmed. I am using a FastCGI SAPI 4.3.9-dev (php4-STABLE-200408091430), and having the same issue:

When a trivial HTML-only web page with a single input item, a textarea, contains more than 1000 characters, the post data is lost by PHP.

When I point the form to a Perl CGI, I can see all the text, but pointing the form to a trivial PHP script that does var_dump on $_REQUEST, I get an empty array.

If I remove a single byte from the text area, presto .. everything looks/works normal.  This was a tad frustrating to isolate.  Now to dig through PHP code to see what the heck is happening at the 1,000th character.

First, I will download the latest snapshot ..

Found it.  A third-party patch was choking.  The problem had nothing to do with the source code shipped with PHP 4.3.9.
To anyone else with this problem, try removing any third-party patches first ..

Marking as Bogus then, as it's not a bug in PHP proper.

The staff could be more kind to say what patches we are supposed to remove, especially when you checked the situation and know the answer. :)

I had the same problem with disappearing POST variables, when their values are larger than 1000 chars. If you had compiled the PHP with hardened flag set ON, you should check the value of "varfilter.max_value_length" in php.ini. By default it is set to 1000 and changing it had solved my problems.
