When statements are evaluated for every loop of with_items. So your when
statement will not prevent ansible from attempting to loop over the value.
You will need to ensure that the value is at least an empty list.
Something like:
- name: Install php and packages from php_packages
yum: name={{ item }} enablerepo=epel state=present
with_items: php_packages|default([])
The side effect, is that you also don't need to check that it is defined,
as the default filter will set it to an empty list which has no iterations,
if the var was not defined to begin with.
