[QWp6t]

@BrandonShutter did you add any extensions to php7? My list differs from yours.

[BrandonShutter]

Yes I added php7.0-xml, and I added that notation now in the original reply, must have been removed when I copied and pasted the table in there.

[BrandonShutter]

Going and installing all the packages that are available here: https://packages.debian.org/search?keywords=php7.0

The packages that I installed are:

  - php7.0-bcmath
  - php7.0-bz2
  - php7.0-imap
  - php7.0-soap
  - php7.0-xml
  - php7.0-xmlrpc
  - php7.0-zip

Leaves me with this comparison:

Note, that installed php7.0-zip fixes the Composer issues found here: https://discourse.roots.io/t/composer-wp-packagist-failure-to-download-on-trellis-deploy/6018/11

I purposely left the imap extension out for Trellis' purposes since we don't need it.

[BrandonShutter]

I figured there was some reason why some weren't added, and that's why I didn't open this up in a PR. This is as close as to the 'same' as php5 was, using available debian packages.

[swalkinshaw]

imap was really the only one not consciously added. There others were mostly left out since stock WP was working fine without them. I wanted the smallest subset possible but it seems like there's still common ones which should be re-added now. xml and zip being the two main ones.

[BrandonShutter]

I nominate we add xmlrpc as well, due to people using the Wordpress app.

Closed by #503

xml, xmlrpc, and zip were added
