Marina Glancy 2dd7290ccb MDL-76362 various: Avoid passing nulls to functions that don't allow nulls
PHP 8.1 is more strict on the parameter type. Functions such as trim(), strlen(), str_replace(), etc
show notice when null is passed as an argument

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.
