Object Oriented Programming with PHP?

[JustinStudios]

I am being trained to write Java. It's wonderful! Now however, I am seeing this "Object Oriented PHP" and want to know, is it just like Java? I know the code is PHP, but do you just call an "Object" by using an include and let it run its course? If so, I am going to start doing this because it just makes more since than copying and pasting files from my library over and over again.

Anyone do OOP PHP? If so I'd love to hear tips and or comments!

Not really like JAVA.
Less strict and yet restrictive.
You can' inherit multiple classes.
here is some pseudo code:

PHP: Select all

//php 4
class myclass {
//properties 
var $str = "string";

//construct
function myclass() {
$this->helloworld();
}

//methods
function helloworld() {
echo "hello world";
}
}
$obj = new myclass(); //prints hello world
$obj->helloworld(); //same again 

Anything else you need to know?

AHHHHHHHHHHHHHHHHHHHHHHHH! That is so fricken cool! I am so going to go learn how to do this!

couple of quick questions though:
1) Where do you store your classes? Can you make a file that has these that you can just import into any page that needs to access them?

2) Do you know where some "Good" resources for this are? Because google shows many resources but finding a good one is rough.

1. Depends on whether you are using PHP4 or PHP5.
If the former (and hopefully), then you can use the awesome fantastic magic function __autoload();
This function will automatically load the class if you haven't included it.
Google __autoload for more info.

2. I have a book but I did know of some good sites, I'll let you know soon.

Sweet! Thanks.. I posted this when you were online because I noticed you mention something about OOP PHP a while back in a post.

Luke's OO PHP article should help.

I started off on the Newsletter team working on a CMS for it, but business picked up that month and I just ran out of time. I believe you were my replacement :P.

Yeah, so far I've managed to create half of 3 CMSs. This one we're working on now should work though
