Like this (note: my comments interspersed, prefixed with ###)
### note the option '-s' -- I don't want to clobber my box!
tomas@trotzki:~$ apt-get -s install '*php*'
NOTE: This is only a simulation!
apt-get needs root privileges for real execution.
Keep also in mind that locking is deactivated,
so don't depend on the relevance to the real current situation!
Reading package lists... Done
Building dependency tree
Reading state information... Done
Note, selecting 'php-horde-timeobjects' for glob '*php*'
Note, selecting 'libphp-jpgraph-examples' for glob '*php*'
Note, selecting 'php-exif' for glob '*php*'
Note, selecting 'php-symfony-form' for glob '*php*'
Note, selecting 'php5-mapscript' for glob '*php*'
Note, selecting 'php-letodms-core' for glob '*php*'
### many, many, MANY lines elided -- roughly 250
Note, selecting 'php-tideways' instead of 'php7.0-tideways'
Note, selecting 'php-xdebug' instead of 'php7.0-xdebug'
### this, of course, isn't bound to end well:
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
php-apcu : Conflicts: php-yac but 2.0.1+0.9.2-1 is to be installed
php-horde-groupware : Conflicts: horde-bundle

installed
php-horde-webmail : Conflicts: horde-bundle

python3-phply : Conflicts: python-phply but 1.0.0-1 is to be installed
E: Unable to correct problems, you have held broken packages.
What's my point?
- Debian has some headstart: it's absolutely worth learning
from them
- Perhaps other distros also know how to play this trick
- Selecting packages by name via some string matching may have
ummm... strange consequences ;-D
Don't get me wrong: I do think Guix goes into the absolutely right
direction, as opposed to the current cloudy container craze.
