Why is POST data truncated by PHP?
<p>I have a pretty big form with many-many items in it. After upgrading to PHP 7, in the new environment some of the POST elements are not received by the server. The <code>$_POST</code> array is not empty, it contains many elements, but some of the elements from the end of the <code>$_POST</code> array is missing. </p>

<p>No error messages appear.</p>

<p>Increasing <code>post_max_size</code> in <code>php.ini</code> (from 8M to 128M) did not help. The data structure itself is not too big, less than 400k, so this shouldn't be the reason. </p>

<p>Why can this be?</p>
