classes

[l0ve2hat3]

if i were to write a class to connect to a database and lets say echo something....

 

would i make class to connect and a class to echo

 

or

 

would i make 1 class and put both functions under the class?

Why in the world would you make a class to echo?  Could you explain exactly what you're trying to accomplish?

 

You would most likely put both in 1 class but again, you need to explain what you're trying to do.

i was just making using a basic example...

 

i am writing a class to tie a mssql based POS system to the web so customers can place orders check inventory and prices...

first, i wouldn't have your class echo anything. leave that to the script using the class

 

as far as 1, 2, or more classes, that will depend on how complex you want to make this. you could easily do this all in one class, but you may want separate classes for each "type" of object you will have. off the top of my head, i can think of the following classes:

POS -> This would be the main class that handles top level stuff

POSItem -> Inventory Item

POSOrder -> Sale/Order

ok i got it... i am not going to have it echo anything.. i was just using that function as an example without going into boring details...

<?php
class msSql {
    private $con;
   
    public function __construct($host, $user, $pass, $db) {
             $con = mssql_connect($host, $user, $pass); 

             mssql_select_db($db, $con);
    }

    public function query($sql) {
          return mssql_query($sql);
   }
}
?>

 

Something like that is a rough example, I am not sure how MSSQL works, so the functions may not be correct. But yea.

if this is your first time with OOP, i would give this a read:

I would recommend drawing up a classes diagram of what you think is right and what you're trying to do.  Check out some existing designs that are similar to yours so you can base your off it.

 

If you have questions you can post it for feedback.  It's hard to say what exactly you should do when we don't know how complex this is going to be.

 

Good luck!
