WEBVTT 00:00.530 --> 00:03.770 I will call you back again to end of the lecture in PHP. 00:03.770 --> 00:10.460 And in this video lecture we go ahead and learn how to write our very first PHP code. 00:17.300 --> 00:17.660 All right. 00:17.660 --> 00:19.490 So we're going to write our PHP code. 00:19.490 --> 00:21.530 And that is the very first thing we're going to do. 00:21.530 --> 00:26.480 Because in the previous lecture we are able to download and install atom on our systems. 00:26.480 --> 00:32.810 And like I told you, if you have any other editor, go ahead and follow up immediately. 00:32.810 --> 00:34.640 Every other thing is just the same. 00:34.670 --> 00:35.240 All right. 00:35.240 --> 00:36.980 So I actually got this atom. 00:37.010 --> 00:42.320 In case you don't have any editor with you, you can go ahead and join me step by step and we'll get 00:42.320 --> 00:43.040 to this point. 00:43.040 --> 00:44.540 So once you install atom. 00:44.570 --> 00:46.100 This is what we're going to have. 00:46.100 --> 00:50.240 And now you can see that everything here is just a welcome message. 00:50.240 --> 00:53.510 I will go ahead and close all these things. 00:53.900 --> 00:56.060 So of course everything right in here. 00:56.060 --> 01:01.080 What are we going to do now is first of all we're going to add a folder because it says we should add 01:01.080 --> 01:02.130 a folder right in here. 01:02.160 --> 01:05.160 Now let's go ahead and add a folder. 01:05.400 --> 01:07.980 Remember we have not created any folder yet. 01:08.010 --> 01:09.870 That means we have to create a folder. 01:09.870 --> 01:15.330 And I'm going to show you where your folder will be created, because that is where PHP will actually 01:15.360 --> 01:18.030 go to go and look for PHP files. 01:18.030 --> 01:24.810 So go ahead and hit on add folder and go over to PC and go over to Local Disk. 01:25.380 --> 01:28.530 Then move to users and they will click on this. 01:28.560 --> 01:33.120 Select the name of your computer and uh open up this. 01:33.150 --> 01:37.530 Then inside here you can be able to add a new folder right here. 01:37.560 --> 01:39.300 I'm going to stretch this open. 01:39.390 --> 01:43.380 And uh let's go ahead and add a new folder right in here. 01:43.440 --> 01:48.120 So I'm going to go over to new and I'm going to add new. 01:48.150 --> 01:52.140 Then the name of the folder I'm going to add I'm going to say w w w. 01:52.140 --> 01:55.110 Now you can add any name of your own choice. 01:55.290 --> 02:01.150 So I just created a folder called w that is the name of a project. 02:01.150 --> 02:03.670 So I'll go ahead and hit on select for that. 02:03.700 --> 02:09.310 So remember that you can do to change this name in case if you want you can go ahead and change this 02:09.310 --> 02:09.790 name. 02:09.790 --> 02:12.970 I just added WW w as my own favorite. 02:13.000 --> 02:18.220 Okay, so it's nothing more to do that now you have been able to create this. 02:18.250 --> 02:25.870 What you need to do is go ahead and right click and create a file right in here I'm going to create 02:25.870 --> 02:26.620 a new file. 02:26.620 --> 02:31.090 And I'm going to call that file name to be any name you want. 02:31.120 --> 02:34.570 Let me go ahead and say site dot PHP. 02:35.020 --> 02:35.560 All right. 02:35.560 --> 02:37.330 So this is site dot PHP. 02:37.480 --> 02:39.340 Go ahead and hit on enter. 02:39.340 --> 02:44.620 And I have sites dot PHP and go over to this folder. 02:44.620 --> 02:50.320 You can see I have the PHP file right in here called phi dot PHP. 02:51.550 --> 02:51.940 All right. 02:51.940 --> 02:53.320 So I have never to create a folder. 02:53.320 --> 02:55.090 And I've been able to create a file. 02:55.090 --> 03:01.460 And this PHP file I just created is exactly the same thing with HTML5. 03:01.550 --> 03:08.810 Remember that our HTML is Hypertext Markup Language and PHP is hypertext preprocessor language. 03:08.840 --> 03:09.260 All right. 03:09.290 --> 03:18.410 Now whatever you are going to do is ensure that you have little knowledge or full knowledge, little 03:18.410 --> 03:19.070 or full. 03:19.100 --> 03:24.620 But you would not going to learn PHP if you don't have knowledge of HTML at all. 03:24.710 --> 03:31.100 So if you don't have knowledge of HTML, our advice will check out our HTML courses on our site and 03:31.100 --> 03:36.920 kick off immediately so you can be able to get the fundamental knowledge of what HTML is all about. 03:36.920 --> 03:44.750 But if you have little knowledge or a pro in HTML, you go ahead and kick off immediately. 03:44.750 --> 03:48.590 So PHP is actually just the same thing. 03:48.590 --> 03:52.340 And we're going to use HTML files right in here. 03:52.370 --> 03:55.520 Now we have been able to create sites dot php. 03:55.550 --> 03:59.190 I'll go ahead and add a word means. 03:59.550 --> 04:02.880 What I'm saying is that I just created a HTML skeleton. 04:02.880 --> 04:06.390 That is where we're going to write our PHP code. 04:06.390 --> 04:13.680 So this HTML skeleton will help us to be able to write PHP code and execute our programs. 04:13.740 --> 04:17.070 Now you have this, uh, stub right in here. 04:17.100 --> 04:23.460 You're going to write your PHP code inside the body of this HTML skeleton. 04:23.910 --> 04:27.900 So whatever you're going to write in PHP is going to be right inside the body. 04:27.900 --> 04:33.390 And let's go ahead and write a simple PHP, uh, code. 04:33.390 --> 04:40.590 And then we execute that and see how that works, because that will enable us to be able to understand 04:40.590 --> 04:42.240 whatever we are doing. 04:42.240 --> 04:49.800 So to write a PHP code, you're going to write a tag, open up a tag and uh, name that to be PHP. 04:49.920 --> 04:54.060 And then you go ahead and close that tag as well. 04:54.070 --> 04:57.670 So go ahead and close that tag. 04:57.670 --> 05:04.240 And, uh, once your tag is closed, that means PHP will run inside here. 05:04.330 --> 05:08.860 So anything you write inside here is your PHP code. 05:09.310 --> 05:13.420 And a simple PHP code is going to write is going to be equal. 05:13.420 --> 05:17.530 Anytime you use the word equal, it means you want to voice out. 05:17.530 --> 05:20.170 That means PHP is about to voice out. 05:20.170 --> 05:25.600 Sunday is going to be able to read whatever it is written after this equal. 05:25.600 --> 05:29.440 So this guy had a right simple hello world. 05:29.440 --> 05:35.080 And once you write that, you close that with a semicolon at the end and you have written your very 05:35.080 --> 05:40.120 first PHP code, what means remains now is to execute this code. 05:40.150 --> 05:42.010 Now go ahead and save your file. 05:42.040 --> 05:45.160 Anytime you write, ensure that you save your file. 05:45.370 --> 05:51.790 Now if you go ahead and run this because this is not dot HTML, it's not going to run that way. 05:51.790 --> 05:54.730 You have to first of all create a server. 05:54.760 --> 06:01.600 Then open up your command prompt and open up a server. 06:01.630 --> 06:04.660 We're going to create a server, but it's going to help us to run this. 06:04.660 --> 06:10.960 And for you to create a server here, what we need to do is you're going to write PHP. 06:10.990 --> 06:12.190 Your command prompt. 06:12.190 --> 06:20.050 And then you're going to put this in the use opaque keys S then call lookup. 06:22.630 --> 06:24.880 Then lookup hosts. 06:24.910 --> 06:31.120 Now once you've added a lookup rules have to add a colon for Tarzan. 06:31.150 --> 06:33.430 Then go ahead and hit enter. 06:33.820 --> 06:35.830 And hit enter. 06:35.830 --> 06:47.020 It will say what is the September 11th PHP 8.3. 11 development server lookup was started. 06:47.230 --> 06:51.220 Now you can see that we have our server right in here. 06:51.220 --> 06:53.000 We have started this. 06:53.060 --> 06:59.420 The development server has actually started and is listening at this point. 06:59.930 --> 07:02.090 HTML blah blah blah. 07:02.120 --> 07:11.810 Lukaku is 4000 copies, so I just copied that and uh, I was able to copy this. 07:12.560 --> 07:17.360 Now I want to start the server again because I have this year I don't want to close this. 07:17.360 --> 07:20.270 Anytime you're working on this, don't ever close this command prompt. 07:20.270 --> 07:21.890 So I'm going to repeat this again. 07:22.130 --> 07:22.580 PHP. 07:24.410 --> 07:31.130 S local host colon 4000. 07:31.130 --> 07:33.380 So I have to start it again. 07:33.380 --> 07:39.950 So at the point of running your PHP code, ensure that your command prompt is always open. 07:39.950 --> 07:42.800 You can actually go ahead and minimize this right. 07:42.830 --> 07:48.020 Then go back to your browser and go ahead and pass all that which you just copy it. 07:48.020 --> 07:50.780 And once I paste that I'll go ahead and hit enter. 07:50.790 --> 07:52.290 And now I hit enter. 07:52.290 --> 07:54.090 I see not found. 07:54.120 --> 07:57.810 The request test source was not found on this server. 07:57.810 --> 08:02.100 So the server we just created is actually having nothing. 08:02.100 --> 08:04.530 And remember that we created this. 08:04.530 --> 08:06.480 So we created a folder right in here. 08:06.510 --> 08:10.200 So that folder is under the user our users. 08:10.200 --> 08:13.470 And the default name is W-w-w. 08:13.500 --> 08:19.830 Now what I want to do is because that is your PHP, we always go, you go ahead and put a backward slash 08:19.830 --> 08:22.950 and then go ahead and say w w w. 08:23.400 --> 08:25.920 So this actually open up some things I've done before. 08:25.920 --> 08:31.980 And backward slash site dot p h p. 08:32.010 --> 08:33.540 So go ahead and remove all this. 08:33.540 --> 08:38.760 And if I go ahead and click on this right now you can see I have Hello world. 08:38.820 --> 08:42.570 All right you guys when I was typing I was actually getting what I've done previously. 08:42.570 --> 08:46.020 And that is actually not a problem. 08:46.020 --> 08:50.860 And we go ahead and uh, media ran with these. 08:50.860 --> 08:56.110 So we've been able to create our server, and our server is currently running around at the moment. 08:56.110 --> 09:02.170 And then we have this folder we created and the file name is uh site dot PHP. 09:02.200 --> 09:03.400 I hope that is cool. 09:03.910 --> 09:06.400 So this is the code we actually used. 09:06.430 --> 09:12.940 We are able to echo out Hello World and we created a folder, a server using our command prompt. 09:12.940 --> 09:15.250 And that server is actually running. 09:15.250 --> 09:17.320 And we are able to get this. 09:17.320 --> 09:19.600 So that is really cool and very interesting. 09:19.600 --> 09:21.250 So I hope that is cool. 09:21.280 --> 09:27.790 Put on this practice with this and show you you run your very first PHP code, and then we move deep 09:27.790 --> 09:30.700 into the course and enjoy the PHP. 09:30.730 --> 09:32.500 We just started right now. 09:32.500 --> 09:38.230 So there are lots of things to learn in this course and just get started and practice whatever we do. 09:38.230 --> 09:43.210 And if you have any question, use the question and answer section and I'm going to get back to you 09:43.210 --> 09:44.230 as soon as possible. 09:44.260 --> 09:45.190 Thank you so much. 09:45.190 --> 09:48.340 And I'm going to see you in the next video lecture.
