The variable msg is defined after the function call, so it is not available when the function executes.
Step 2: Verify variable availability at call time
Variable msg is not defined before calling print_msg, so $msg inside the function is unset.
Step 3: Identify actual error
Variable msg must be defined before the function call to be accessible.
