Bear in mind that .htaccess has a very narrow use and it's kind oh thing
Apache2 related and not PHP specific!

Personally I like the idea of setting ini directives via environment
variables but not by a complex syntax in ini files but rather by looking up
for a directive by environment variable name and setting it up directly for
instance:

PHP_MEMORY_LIMIT=3D1G php script.php

Being equivalent of:

php -dmemory_limit=3D1G script.php

This would allow to avoid changes in php.ini file in containers with php or
php-fpm like Docker ones and to adjust ini directive values by simple
environment variables.

I believe there should be no two ini directives which could be ambiguous
like for eg. "memory_limit" and "memory.limit" and cause issues on ini
directives lookup by env variable name like PHP_MEMORY_LIMIT.

Cheers,
