To simplify packaging some new macros should be included into PHP7.

Please include those changes in the upcoming SRs of maintained leap versions
when possible!

There is an intermediate package in
https://build.opensuse.org/package/show/server:php:applications/php7-macros

Those are the new macros:
%php_pearxmldir /var/lib/pear
%pear_phpdir  %(%{__pear} config-get php_dir  2> /dev/null || echo undefined)
%pear_docdir  %(%{__pear} config-get doc_dir  2> /dev/null || echo undefined)
%pear_testdir %(%{__pear} config-get test_dir 2> /dev/null || echo undefined)
%pear_datadir %(%{__pear} config-get data_dir 2> /dev/null || echo undefined)
%pear_cfgdir  %(%{__pear} config-get cfg_dir  2> /dev/null || echo undefined)
%pear_wwwdir  %(%{__pear} config-get www_dir  2> /dev/null || echo undefined)
%pear_metadir %(%{__pear} config-get metadata_dir 2> /dev/null || echo
undefined)
