What is the code to make > sure the password entered is NOT case-sensitive? when you store the password, you can store it as all upper or all lowercase, then when comparing against the stored value, do the same operation to the value supplied from the user, and compare those. and you dont have to modify the original value if you dont want to, when you store it. just remember to alter both the stored value and the user-supplied value when doing comparisons. /// here is an example comparison // get password value from db for user, put it in $storedPassword // suppose the value the user supplied in a form is in variable $userSuppliedPassword // now for the case insensitive comparison if(strtolower($storedPassword) == strtolower($userSuppliedPassword)) // passwords are the same else // passwords are different also note in the above example, there is no encryption of the password, which you almost certainly want to have ;) -nathan
