Pick up a general book on OOA/D development. IMHO, the advantage of OO is to modularize your code with encapsulation(buzz word). Basically meaning that as long as your interface to an object does not change, it does not matter to the *outside world* what you do behind the scenes. This is especially beneficial for abstracting layers (as someone else pointed out with the DB abstraction), as well as working within teams of developers. Done right it enhances all the *ilities* of software development, done wrong it is a horrific mess of spaghetti! Another advantage could be design *might* be easier because UML exists as a nicely featured modeling language which maps very nicely to classes in OO. When all is said and done it is another tool in software development. It has its purposes and when wielded by persons who know how best to use it, it is quite a good method. But be your own judge, and read some about it!ok, about five minutes ago i decided to learn classes and delve into php's oop side. what i came up with was this... //start example code class newsletter { function send ($email,$subject,$message) { if ($email) { echo("the following message was sent to: $email <br> subject: $subject<br><br> $message");} else {echo("failure"); } } } $new = new newsletter(); $new->send("test@xxxxxxxxx", "test class", "test class worked, i have passed and failed the test."); //end code example ..and this seems to work fine, i could easily add the mail function and insert real variables into send() but what i don't understand is i could also easily do this without a class... so i guess the real question is what are some real life examples of class usage and why is it used as opposed to regular non oop? thank you for any input into the subject that you may have.
Another *real world* example might be taking the DB abstraction a little further. Represent all your tables as classes. This gives you the ability to properly scrub, validate data before assigning it, allows you to automatically persist the data (if you choose) when the class goes out of scope, gives easy access of data to people who need not concern themselves with the DB schema, etc.. Really a nice tool for this case, especially when you inherit a schema which is less the obvious ;-)
