Having those files please adjust the following tasks.
When the user fills out the registration, all information is inserted into a database table.
When the user signs in, all information is verified from the database table.
You can either create your own table on your machine or use the demo server table for testing. Remember the table name and the fields must be exactly as shown below.
If you are using your own table, you must change the connection info as shown below before uploading to the demo server. Then you must test to make sure it works correctly on the demo server.
The table name will be 'account'.
The fields in the table are:
username - 20 char
password - 50 char
name - 20 char
email - 50 char
Make sure that all field names are the same upper and lowercase letters as shown above.
The password will still be encrypted when stored in the database.
You must insert data into the table using your program. Do not assume anything is on the table.
When creating userids and passwords, use something unique, as your classmates will be sharing the same table.

</body>
</html>
Sample output:
The statements below "Register For account" heading are for testing the database operations, they can be removed from dbconn.php file.
Cant create database means that already database is existing.
Error creating table means that the table "account" is already created.
Test Cases:
1.
2.
MH was the user name given for testing.
