php-intl is missing - or - how to install extensions?

[ieugen]

Hi,

I'm using version 0.15.2 of wordpress-starter and in one place I use MessageFormatter to handle plurals correctly.

Because of that I get Uncaught Error: Class 'MessageFormatter'

I believe php-intl is missing and I will look into adding that, however, I imagine that I might not be the only one with the issue and having the extensions installed might be good.

Since there are a lot of extensions, it might be ok to have a way to install them on build.

I'll come back with feedback.

Thanks,

Looking at the Dockerfile for php-7.1 image I managed to install intl but it was not easy. I got some pointers from [1].

p.s. Debian Stretch is out with php7.

[1] docker-library/php#57

Adding extensions is easy, it just needs to be done during the initial compilation. If you'd like, try adding the extension to this chain of extensions, compile the dockerfile, and let me know if it works. I have no problem adding it in.

Hi,

It might not be that simple for all users. Some extensions require extra dependencies as well.

If I have a running setup, how can I rebuild my image to include the extra extensions?

In the current setup I believe I have to publish a new image.

host $ docker-compose exec -it wordpress /bin/bash
wordpress # apt-get install php7.0-intl
wordpress # docker-php-ext-install intl
wordpress # service apache2 reload

I remember the image was based on Debian Jessie which has php5.6 but I will try. Thanks.
