PHP Bugs: #37276: problems witch $_POST array
A PHP 5.1.3 bug caused $_POST arrays with nested keys (like `masivasid[id_1]` and `masivasid[id_2]`) to be parsed incorrectly when forms were submitted with `multipart/form-data` encoding, resulting in malformed array structures where later keys would be nested under earlier ones instead of existing at the same level. The issue affected all Linux systems tested and did not occur with GET requests, breaking functionality in applications like phpMyAdmin, with users identifying the likely culprit as the `php_register_variable_ex` function in the PHP source code.
