It is another approach, and like any approach, it has its advantages and
disadvantages.
One of the big advantages is you can put all of your validation code in
the class - for instance, if you have a User class with username,
password and email, the three fields can be validated in the class
itself. This means all of your validation for the three fields is in
one place. The class itself is bigger, but there's less duplication of
code (i.e. you don't have to verify the password when they sign up or
when they try to change their password). Overall, you typically end up
with fewer lines of code and fewer bugs due to the less duplication.
And properly designed, you could take this User class and drop it into
another website unchanged, so you already have all the information
available.
Other advantages are things like isolating database calls from the rest
of the program - put all of your database-specific stuff in a class,
then the class object represents the connection to the database. The
mysqli_xxx interface is a good example of this for MySQL.
You can simulate OO with just functional coding, but you don't get the
full advantages of OO unless you design your code to use OO.
With that said - I like OO, but I still do functional programming also.
Like anything else, neither is best in every instance. Your best bet
is to become familiar with OO and try it out. See where it will work
for you and where it won't.
