Bug: php.ini manager cannot set negative numbers

I try to use the php.ini manager to set always_populate_raw_post_data = -1, as the php documentation is instructing me to do here: https://php.net/manual/en/ini.…ys-populate-raw-post-data

Unfortunately LC is not able to create a valid value because the site fails with an error 500. This most likely needs to be a number without quotes (not a string) and the manager fails to accept negative numbers.

Now I need to compile a lower PHP version to make this work, because the impossible permissions make it very unpractical to change the the conf/php.ini manually.

Yes as workaround the "string" format can be chosen. The 500 error was caused by something else.
