On other systems, this may be different, for example on Debian 10 Buster it should be:
php_value include_path .:/var/www/translate5/library/zend/:/usr/share/php5:/usr/share/php:/usr/share/php7.3-common
Please be aware, that you have to check your webserver and this apache configuration regarding security, if you oppose your translate5 instance to the internet. Your security is your responsibility and can not be covered by this manual.
