(NEW 2019 VIDEO IN DESC!!!) What Is Object Oriented PHP | PHP Tutorial | OOP PHP | mmtuts

[00:00] how it going guys I'm back to another

[00:02] series on how to do op oriented

[00:03] programming using PHP code now because

[00:07] this is the first episode in optic

[00:08] oriented programming I'm going to spend

[00:10] this episode explaining what exactly

[00:12] optic oriented programming is because

[00:14] it's very important that you guys

[00:16] understand what it is if you have never

[00:18] done anything with objectoriented

[00:19] programming before so if you're

[00:21] completely familiar with objectoriented

[00:23] programming you don't need to watch this

[00:25] episode The reason I want to do a small

[00:27] episode on just explaining what exactly

[00:29] it is is because I remember back when I

[00:31] was learning object oriented programming

[00:33] you know back when I was studying my

[00:35] bachelors um the teacher had a specific

[00:38] way of explaining optic oriented

[00:40] programming that didn't make sense to

[00:42] the entire class so it's very important

[00:45] to me that I understand this in a way

[00:46] that you guys understand it and know

[00:48] exactly why we need to use op oriented

[00:51] PHP programming versus the other way we

[00:54] do it in the past okay now when it comes

[00:57] to PHP programming the way been doing it

[01:00] in my other series that's just called

[01:02] PHP um we use something called procedure

[01:05] programming now what that means is that

[01:08] when we have a website such as just a

[01:10] regular website with a login system we

[01:12] would just go ahead and create the PHP

[01:14] code and insert it inside the document

[01:17] whenever we needed to use it meaning

[01:19] that if I had a sign up form inside my

[01:21] website I would just create the PHP code

[01:24] inside the HTML page or inside the PHP

[01:27] document uh where I had the sign up for

[01:30] form whereas in object going into phsp

[01:33] programming we create separate documents

[01:36] only meant for PHP code that has

[01:39] something in it called classes now

[01:41] classes contain something called

[01:43] properties and methods that we use

[01:46] regarding one specific thing inside our

[01:48] website now if that sounded confusing it

[01:51] will sound confusing if you've never

[01:53] done anything with optic ored PHP

[01:54] program before so don't get scared that

[01:57] you don't understand what classes and

[01:59] properties methods are just go ahead and

[02:02] follow the lessons and you will

[02:03] understand in no time so the basic idea

[02:06] here is that let's say we have this

[02:07] login system inside a website and I need

[02:10] to create the PHP code for this login

[02:12] system now what I can do instead of just

[02:14] creating the code where I need to use it

[02:16] inside my phsp document I'm going to go

[02:19] ah and create a separate document that

[02:20] has a class which is just a very big

[02:24] container to a lot of code that I use

[02:27] regarding login systems so this class

[02:30] might be called

[02:31] login now inside this login class we

[02:34] have properties and methods which is

[02:36] another way of saying we have variables

[02:38] and functions that are saved inside this

[02:41] class now don't get me wrong properties

[02:43] and methods are not the same as

[02:46] variables and functions but they work in

[02:48] a very similar way okay so inside this

[02:51] class regarding login systems we have

[02:54] code that does something regarding the

[02:56] login system and because we do it this

[02:59] way way if I were to do anything else

[03:02] inside the website you know in another

[03:03] page regarding a sign up form I can

[03:06] reuse the code inside the class rather

[03:08] than creating the code again inside the

[03:11] website okay so we can actually reuse

[03:13] code again and again and again which is

[03:16] one of the benefits from using op gr to

[03:18] PHP

[03:19] programming now another benefit from

[03:21] optic gr to PHP programming is that when

[03:24] you if you want to work at a marketing

[03:27] agency you know a place where they

[03:28] actually create websites for companies

[03:29] and that sort of thing it's pretty much

[03:32] a standard today that you need to

[03:34] understand after gr to PHP programming

[03:36] because oop which is what we call optic

[03:39] oriented PHP programming is a format

[03:42] that all programmers understand with

[03:44] procedural code I have one way of coding

[03:47] it another programmer has another way of

[03:49] coding it meaning that we might not

[03:51] understand the code that each you know

[03:53] each person wrote so op to go into PHP

[03:55] programming kind of solves that problem

[03:58] because we need to understand with other

[04:00] people program when we have other people

[04:02] that we work with now you might be

[04:04] asking well is optic ored PSP

[04:06] programming better than procedural

[04:08] programming you know we just create the

[04:09] code wherever we need to use it inside

[04:11] our document well if the code is just

[04:14] meant for you to use and you just create

[04:16] the code for small applications then no

[04:19] it doesn't matter if you do optic rer

[04:21] phsp programming or procedural

[04:23] programming like a login

[04:25] system I would say it's borderlining you

[04:27] know where you need to start considering

[04:29] us using optic run to phsp programming

[04:31] because now you're starting to create a

[04:33] lter application but I just want to

[04:35] highlight that a lot of people at least

[04:37] a lot of programmers don't believe that

[04:39] optic ored PSP programming is better

[04:42] than procedural some people think they

[04:44] do exactly the same thing where a person

[04:46] like me think that optic rer PSP

[04:49] programming if used right can do a lot

[04:52] more beneficial things when it comes to

[04:54] larger applications so if you're

[04:56] watching this series and thinking well

[04:58] optic R to PSP programming sounds much

[05:00] too complicated or might be too

[05:02] difficult to learn versus what you're

[05:04] actually getting out of it then you

[05:06] shouldn't look at it as a bad thing to

[05:09] just want to go with procedural

[05:10] programming just remember that if you

[05:12] want to work with this in the future

[05:14] you're going to need to look into optic

[05:16] R into phsp programming but it's really

[05:18] not that difficult to learn I just want

[05:19] to empathize that because it really

[05:21] depends on who's explaining it to you

[05:23] now another thing I want to mention

[05:25] regarding optic run into PHP programming

[05:27] which is one thing that if you guys have

[05:29] actually been good Googling it looking

[05:30] for tutorials is that when you go to

[05:33] different tutorial sites object oriented

[05:36] phsp programming will be taught

[05:39] differently by pretty much everyone and

[05:41] the reason for this is that we have

[05:43] different patterns in optic R to PHP

[05:46] programming now what patents means is

[05:49] that when you have optic PHP programming

[05:52] you have a specific formula or a

[05:54] specific pattern that you create the

[05:57] code in meaning that if I were to learn

[05:59] this from one website uh they might be

[06:02] using something called Constructor

[06:03] patents where another tutorial series

[06:06] might not be using Constructors which is

[06:08] something that we will be talking about

[06:09] in this series here because Constructors

[06:11] seem pretty important when it comes to

[06:13] having the proper format of op ored PHP

[06:16] programming but it's different what

[06:19] people teach you when it comes to op

[06:21] ored PHP programming so I just want to

[06:23] mention before you get started on this

[06:25] series that what we're going to be doing

[06:27] is we're going to go ahead and use

[06:29] what's called an MVC pattern which

[06:31] stands for model view controller and

[06:34] it's a pattern that was created quite a

[06:35] while back which was used mainly for

[06:38] other types of programming languages but

[06:41] has been incorporated into PHP when it

[06:43] comes to oop programming and we're going

[06:46] to go and using this series here now in

[06:48] the next episode I will be explaining

[06:50] what exactly an MVC model is you know

[06:52] model view controller and why we need to

[06:55] do it this way at least when it comes to

[06:56] my tutorial series here in the future we

[06:59] might might be looking into other design

[07:01] patterns but for now in the beginning

[07:03] here we're going to focus on the NVC

[07:05] pattern since it's pretty popular out

[07:06] there so I hope you guys enjoyed and

[07:09] I'll see you guys next

[07:13] time
