[0:00] how it going guys I'm back to another
[0:02] series on how to do op oriented
[0:03] programming using PHP code now because
[0:07] this is the first episode in optic
[0:08] oriented programming I'm going to spend
[0:10] this episode explaining what exactly
[0:12] optic oriented programming is because
[0:14] it's very important that you guys
[0:16] understand what it is if you have never
[0:18] done anything with objectoriented
[0:19] programming before so if you're
[0:21] completely familiar with objectoriented
[0:23] programming you don't need to watch this
[0:25] episode The reason I want to do a small
[0:27] episode on just explaining what exactly
[0:29] it is is because I remember back when I
[0:31] was learning object oriented programming
[0:33] you know back when I was studying my
[0:35] bachelors um the teacher had a specific
[0:38] way of explaining optic oriented
[0:40] programming that didn't make sense to
[0:42] the entire class so it's very important
[0:45] to me that I understand this in a way
[0:46] that you guys understand it and know
[0:48] exactly why we need to use op oriented
[0:51] PHP programming versus the other way we
[0:54] do it in the past okay now when it comes
[0:57] to PHP programming the way been doing it
[1:00] in my other series that's just called
[1:02] PHP um we use something called procedure
[1:05] programming now what that means is that
[1:08] when we have a website such as just a
[1:10] regular website with a login system we
[1:12] would just go ahead and create the PHP
[1:14] code and insert it inside the document
[1:17] whenever we needed to use it meaning
[1:19] that if I had a sign up form inside my
[1:21] website I would just create the PHP code
[1:24] inside the HTML page or inside the PHP
[1:27] document uh where I had the sign up for
[1:30] form whereas in object going into phsp
[1:33] programming we create separate documents
[1:36] only meant for PHP code that has
[1:39] something in it called classes now
[1:41] classes contain something called
[1:43] properties and methods that we use
[1:46] regarding one specific thing inside our
[1:48] website now if that sounded confusing it
[1:51] will sound confusing if you've never
[1:53] done anything with optic ored PHP
[1:54] program before so don't get scared that
[1:57] you don't understand what classes and
[1:59] properties methods are just go ahead and
[2:02] follow the lessons and you will
[2:03] understand in no time so the basic idea
[2:06] here is that let's say we have this
[2:07] login system inside a website and I need
[2:10] to create the PHP code for this login
[2:12] system now what I can do instead of just
[2:14] creating the code where I need to use it
[2:16] inside my phsp document I'm going to go
[2:19] ah and create a separate document that
[2:20] has a class which is just a very big
[2:24] container to a lot of code that I use
[2:27] regarding login systems so this class
[2:30] might be called
[2:31] login now inside this login class we
[2:34] have properties and methods which is
[2:36] another way of saying we have variables
[2:38] and functions that are saved inside this
[2:41] class now don't get me wrong properties
[2:43] and methods are not the same as
[2:46] variables and functions but they work in
[2:48] a very similar way okay so inside this
[2:51] class regarding login systems we have
[2:54] code that does something regarding the
[2:56] login system and because we do it this
[2:59] way way if I were to do anything else
[3:02] inside the website you know in another
[3:03] page regarding a sign up form I can
[3:06] reuse the code inside the class rather
[3:08] than creating the code again inside the
[3:11] website okay so we can actually reuse
[3:13] code again and again and again which is
[3:16] one of the benefits from using op gr to
[3:18] PHP
[3:19] programming now another benefit from
[3:21] optic gr to PHP programming is that when
[3:24] you if you want to work at a marketing
[3:27] agency you know a place where they
[3:28] actually create websites for companies
[3:29] and that sort of thing it's pretty much
[3:32] a standard today that you need to
[3:34] understand after gr to PHP programming
[3:36] because oop which is what we call optic
[3:39] oriented PHP programming is a format
[3:42] that all programmers understand with
[3:44] procedural code I have one way of coding
[3:47] it another programmer has another way of
[3:49] coding it meaning that we might not
[3:51] understand the code that each you know
[3:53] each person wrote so op to go into PHP
[3:55] programming kind of solves that problem
[3:58] because we need to understand with other
[4:00] people program when we have other people
[4:02] that we work with now you might be
[4:04] asking well is optic ored PSP
[4:06] programming better than procedural
[4:08] programming you know we just create the
[4:09] code wherever we need to use it inside
[4:11] our document well if the code is just
[4:14] meant for you to use and you just create
[4:16] the code for small applications then no
[4:19] it doesn't matter if you do optic rer
[4:21] phsp programming or procedural
[4:23] programming like a login
[4:25] system I would say it's borderlining you
[4:27] know where you need to start considering
[4:29] us using optic run to phsp programming
[4:31] because now you're starting to create a
[4:33] lter application but I just want to
[4:35] highlight that a lot of people at least
[4:37] a lot of programmers don't believe that
[4:39] optic ored PSP programming is better
[4:42] than procedural some people think they
[4:44] do exactly the same thing where a person
[4:46] like me think that optic rer PSP
[4:49] programming if used right can do a lot
[4:52] more beneficial things when it comes to
[4:54] larger applications so if you're
[4:56] watching this series and thinking well
[4:58] optic R to PSP programming sounds much
[5:00] too complicated or might be too
[5:02] difficult to learn versus what you're
[5:04] actually getting out of it then you
[5:06] shouldn't look at it as a bad thing to
[5:09] just want to go with procedural
[5:10] programming just remember that if you
[5:12] want to work with this in the future
[5:14] you're going to need to look into optic
[5:16] R into phsp programming but it's really
[5:18] not that difficult to learn I just want
[5:19] to empathize that because it really
[5:21] depends on who's explaining it to you
[5:23] now another thing I want to mention
[5:25] regarding optic run into PHP programming
[5:27] which is one thing that if you guys have
[5:29] actually been good Googling it looking
[5:30] for tutorials is that when you go to
[5:33] different tutorial sites object oriented
[5:36] phsp programming will be taught
[5:39] differently by pretty much everyone and
[5:41] the reason for this is that we have
[5:43] different patterns in optic R to PHP
[5:46] programming now what patents means is
[5:49] that when you have optic PHP programming
[5:52] you have a specific formula or a
[5:54] specific pattern that you create the
[5:57] code in meaning that if I were to learn
[5:59] this from one website uh they might be
[6:02] using something called Constructor
[6:03] patents where another tutorial series
[6:06] might not be using Constructors which is
[6:08] something that we will be talking about
[6:09] in this series here because Constructors
[6:11] seem pretty important when it comes to
[6:13] having the proper format of op ored PHP
[6:16] programming but it's different what
[6:19] people teach you when it comes to op
[6:21] ored PHP programming so I just want to
[6:23] mention before you get started on this
[6:25] series that what we're going to be doing
[6:27] is we're going to go ahead and use
[6:29] what's called an MVC pattern which
[6:31] stands for model view controller and
[6:34] it's a pattern that was created quite a
[6:35] while back which was used mainly for
[6:38] other types of programming languages but
[6:41] has been incorporated into PHP when it
[6:43] comes to oop programming and we're going
[6:46] to go and using this series here now in
[6:48] the next episode I will be explaining
[6:50] what exactly an MVC model is you know
[6:52] model view controller and why we need to
[6:55] do it this way at least when it comes to
[6:56] my tutorial series here in the future we
[6:59] might might be looking into other design
[7:01] patterns but for now in the beginning
[7:03] here we're going to focus on the NVC
[7:05] pattern since it's pretty popular out
[7:06] there so I hope you guys enjoyed and
[7:09] I'll see you guys next
[7:13] time
