What can cause $_POST data to be incomplete

Question

I have a simple basic HTML form with about 1500 fields. 500 rows have text entries. When form is submitted, $_POST contains only about 130 entries of those 500 rows. post_max_size is high, so it's not that. You can see the barebone sample here:

http://www.dadilja.rs/test.php

If you check the source after submit, you will see that the $_POST data contains entries only until letter F.

So I'm figuring it's some server setting, since there's only HTML on the page, and the behaviour is the same on two different servers - probably some generic setting. If you check the Web console, and inspect Request Body, you will see that the form submits all the data. Any ideas?

A "simple" HTML form with about 1500 fields is something of an oxymoron — Mark Baker, Mar 22 '14 at 15:43
simplicity is the opposite of complexity. this form is not complex, it is long — srgb, Mar 22 '14 at 17:36
If I see a form with that many fields, I leave that website alone — Mark Baker, Mar 22 '14 at 17:53

Check your php.ini max_input_vars. Default is 1000.
