it easy to Authentication

first you need to create table like this

Roll_ID | Roll

------------------------

1 | Admin

2 | User

3 | Manager

then create registration table like this

Tbl_Registration

Register_ID | Username | Password | Roll_ID

1 | Sagar | 123456 | 1

2 |Sameer | 123456 | 1

3 | Richa | 123456 | 2

4 | John | 123456 | 3

5 | Stiven | 123456 | 3

if someone try to login then check her / his Username , password.

if username and password is found in database then check Roll_ID

if(Roll_ID == 1)

{

//Call Admin Page

}

else if(Roll_ID == 2)

{

// Call User page

}

else if(Roll == 3)
