ini setting zend.assertions should changeable PHP_INI_PERDIR without restriction

Description

Currently, if the ini setting zend.assertions is set to -1 in php.ini, it cannot be set to a different value in per-directory configuration file (PHP_INI_PERDIR) .user.ini or .htaccess (and vice versa).

I want to be able to change zend.assertions PHP_INI_PERDIR without restriction, for the following reasons:

1. I have not always write access to php.ini;
2. I don’t know the PHP_INI_PERDIR equivalent of
   <?php if (ini_get('zend.assertions) !== '-1') ini_set('zend.assertions', '1'); ?>
   in order to avoid an E_WARNING.

(Note that there is at least one other ini setting, namely short_open_tag, that also modify the result of compilation, but that is nevertheless changeable PHP_INI_PERDIR; from which I infer that my request is not unreasonable.)

El issue concierne a zend.assertions en php.ini y a la configuración por directorio en .user.ini o .htaccess; comienza rastreando cómo gestionan estos contextos ese ajuste. Se considera terminado cuando un valor establecido en un contexto puede cambiarse a otro sin la restricción actual ni el E_WARNING resultante.
