Web Design and Programming Pt 10 PHP & OOP

Here I cover Object Oriented PHP. I explain encapsulation, classes, objects, public, private, constructors, destructors, __set, __get and more.

@JamesRCoston Yes, I've read all of the books that supposedly cover OOP in PHP. PHP isn't a OOP language, but it does allow you to implement some oop principles. I'll get into how you can incorporate design patterns into php some day. That is actually pretty useful.

@sethchilds Constants can't have access specifiers like private, public or protected. They also can only have either the value of a string or number. The constant is part of the class definition and not the objects that you create. That's why you use the scope operator (::) to access it. Hope that helps. Thanks

@SamuelLockyer I really liked the Larry Ullman book on PHP. I pretty much learned everything else through experience over the years. Yes there are tons of different ways you can use the magic methods. I don't use them very often in day to day coding though

[durnik]

These videos are excellent, and much appreciated. You are right about books not covering __set and _get thoroughly. __construct and __destruct are relatively clear, but the other 2 magic methods are for more confusing, and are barely covered in the THREE books I own. Thanks again!

@sondano Thanks for pointing that out. Deciding on what versions to do tutorials on is often my biggest decision.

[derekbanas]

@metardd Thanks. Most people on you tube are trying to make money. That's why they make a ton of short tutorials. The more views they get, the more money they make. I don't think it's conducive to actually learning though. Drupal is just php, JavaScript and jquery like wordpress. As soon as I can I'll cover it.

[derekbanas]

@robotworkz Thank you. I'm glad you like them

[derekbanas]

@metardd I can do that eventually. I'm kind of backed up. I did the only tutorials on making wordpress themes and plugins from scratch. You may like those. They are free on my yt channel :)

[derekbanas]

@SamuelLockyer The only way you'll learn to program is through practice. A professor will teach you the basics, efficient coding and design patterns. In the real world you don't have time to be perfectly efficient and if you're working in a group you can't trust that everyone will understand your design patterns. If I was you I would set a goal that you want to make Facebook. It actually isn't very hard. By the end of that project you'll know more about programming than your teacher :)

There were a few tips here that helped me a lot. Thanks

[JamesRCoston]

PHP and MySQL Web Development Fourth Edition has amazing coverage of OOP in PHP. I suppose the lack of coverage in books is due to how young the OO functionality is in PHP.

[metardd]

I really like your tutorials. Is there any way you can do a series on Drupal? Specifically how to create your own Drupal module. I can't seem to find any video tutorials on it, for free at least.

[metardd]

@derekbanas Yeah I noticed that you did some Wordpress tutorials but I'm trying to become a Web Developer and I've decided that I will focus on Drupal cause I'm already familiar with that cms since all my personal websites I have set up using Drupal. So I already know a few things about drupal but I don't know how to make custom modules. I really like your style of teaching, I find that it's easier to understand the way you do it compared to other folks who do tutorials.

ur class is very interesting
thankyou

[alexandershekhtman]

when you change $name to also private instead of public, why do the constructors get called twice:
__construct was called
__set was called for name
__get was called for name
__set was called for age
__get was called for age
9
The dogs name is Grover
The dogs age is 9
The pounds ID number is 12345
__destruct was called

[DmitriuTT]

There are no links between __set, __get with setAge, getAge. How does it work?

[MrLangam]

I'm getting a warning and notice messages for some reason. Everything is working fine.

Warning: Missing argument 1 for Animal::__construct(), called in on line 54 and defined in C:\.... on line 29
Notice: Undefined variable: age in C:\.. on line 31

[derekbanas]

No because php isn't an oop language, but you can fake it
