How do you create a login system using PHP?

Answer 1

Here are the steps

1. Create a register form using html form elements. Keep them minimum like username, password, confirm password, email and 2-3 more fields
   
2. On Submit button use validation to check form input possibly using javascript or php side validation
3. Save the details from form submission in database
4. Login will check for username/email and password
5. Sessions will store login details
