-- Insert Sample Data
-- Admin: 1234567890 / admin123
-- User: 9876543210 / user123
-- Note: In a real app, passwords should be hashed. For this sample, we are storing plain text as per implied simplicity, 
-- but I will use simple hashing in the PHP code for better practice if possible, 
-- however the prompt implies simple login. I'll stick to simple text for the sample to match the prompt's "plain core PHP" simplicity expectation, 
-- or better, I will use password_hash in the seed and verify in login.
