Alpine Linux is a very common Linux distribution used in Docker images. But it has one problem. The official repository is missing the libiconv package needed to compile the ICONV PHP extensions. There is one very well known thread that addresses this bug docker-library/php#240. This is how Alpine Linux makes a functional extension of ICONV. One solution exists, LD_PRELOAD is used for this environment. RUN apk add gnu-libiconv --update-cache --repository http://dl-cdn.alpinelinux.org/alpine/edge/testing/ --allow-untrusted ENV LD_PRELOAD /usr/lib/preloadable_libiconv.so php You can install the gnu-libiconv package from the test repository to Alpine, but PHP will not recognize it. If I use the iconv function and I have this package installed in Alpine, everything works OK but phpinfo () says enabled => unknown. That's why I removed this rule from the checker. I think that a sufficient rule to verify the functionality of the ICONV extension is already applied: @iconv ('UTF-16', 'UTF-8 // IGNORE', iconv ('UTF-8', 'UTF-16 // IGNORE' test ')) ===' test '.
