Eloy Lafuente (stronk7) 4621917c62 MDL-67114 core: php74 fix. Fix use of scalar as array in core
There are various places where it's not guaranteed that the
variable being used is array, and instead, can be null, bool, int...

We need to check that because php74 warns about it.

Where possible we have used the coalesce operator as
replacement for isset() ternary operations.

ENROLMENT MODULES
-----------------

(Yes, that's the correct English spelling  ;-) )

All enrolment modules must extend base class enrol_plugin
which is defined in lib/enrollib.php. You can find documentation
of each method in the base class.
