Thanks, is this variable is intended to use only with RedHat ?
Formulas fails in my side because I run it on a Debian server.
After investigation I found this 'enable_php_repo' var is only set for RedHat:

php-formula/php/ng/installed.jinja

Line 75 in 0c92324

{% elif grains['os_family'] == "RedHat" and (state == 'cli' or state == 'fpm' or state == 'php') %}

but it used outside this if elsif statement ...

As documented on pillar, there is an 'use_external_repo' and 'external_repo_name' vars. What is different with this new var?

Same as Issue #169

@sticky-note can you test the proposed solution

It seems to work but #166 seems to introduce a mistake as it modify behavior for RedHat only ...

It works here too, properly fixes bug introduced by #166 for non-RedHat.

Fix kinda required for non-RedHat use.
