WEBVTT 00:00.280 --> 00:04.480 Hey, I'm Piotr and welcome to a different kind of PHP course. 00:04.800 --> 00:08.680 We are skipping the boring theory and jumping straight into action. 00:08.680 --> 00:13.960 In the next five minutes, we'll get the environment set up and you'll run your very first PHP program 00:13.960 --> 00:15.760 on your own computer. 00:16.160 --> 00:17.960 I'll show you how simple it is. 00:18.280 --> 00:19.000 Ready? 00:19.360 --> 00:20.360 Let's dive in. 00:22.400 --> 00:27.720 To run PHP programs on your computer, you need to have PHP installed on it. 00:28.200 --> 00:35.920 Historically, installing and setting up PHP was something that caused a lot of issues, especially 00:35.960 --> 00:39.320 for beginners, but not only for beginners. 00:39.880 --> 00:45.160 There were ready made packages like Samp and Vamp and those are still in use. 00:45.160 --> 00:49.120 So if you have one of those, you should be set up already. 00:49.640 --> 00:52.120 But I'd like to show you something new. 00:52.760 --> 01:00.400 This PHP website has this one single command that should run an installation script that will get you 01:00.400 --> 01:07.030 set up Setup with PHP and composer, and this essentially means everything that you need to develop 01:07.030 --> 01:12.110 in PHP, and especially everything that you need to go through this course. 01:12.630 --> 01:18.030 This command is available for Mac, for windows, and for Linux. 01:18.790 --> 01:21.590 So let me follow the instructions for my system. 01:22.110 --> 01:23.950 I'm just going to copy this command. 01:25.110 --> 01:26.270 So I hit copy. 01:26.270 --> 01:31.870 And next up I need to open spotlight and run the terminal. 01:32.070 --> 01:35.310 You follow the instructions for your system. 01:36.390 --> 01:45.830 So I'm typing terminal and the first thing I'm going to do is I will check if I have PHP already by 01:45.830 --> 01:47.270 running PHP v. 01:47.710 --> 01:54.670 I don't have it because I literally removed it minutes ago, so I can follow the instructions the same 01:54.670 --> 01:55.590 way as you do. 01:56.390 --> 01:58.910 Now let me paste this command and hit enter. 01:59.670 --> 02:02.260 Well, I had something installed previously. 02:02.260 --> 02:03.540 So it's asking me. 02:03.540 --> 02:10.260 I confirm with yes, you probably would not be asked this question and now we just need to wait for 02:10.260 --> 02:13.540 it to download the PHP binary and composer. 02:13.900 --> 02:18.460 That should be pretty quick and we should have PHP available. 02:20.460 --> 02:25.580 We might want to restart the terminal to make sure that this is applied. 02:27.740 --> 02:31.220 And then let's run this php v again. 02:31.900 --> 02:36.660 You should see that you have the recent PHP version installed. 02:38.940 --> 02:41.860 So at this point we're already going to do some coding. 02:42.020 --> 02:44.060 To code you need a code editor. 02:44.220 --> 02:47.180 So grab Visual Studio Code or cursor. 02:47.500 --> 02:54.740 Both come with some amount of built in AI features that might be available for free. 02:55.460 --> 03:03.170 So I've already created the first PHP file you can create in any folder of your choice. 03:04.410 --> 03:08.650 Every PHP file starts with PHP directive. 03:09.730 --> 03:13.090 So guys, welcome in the world of PHP. 03:13.890 --> 03:15.730 Let's already create something. 03:15.730 --> 03:20.930 This would be super simple and remember you are not expected to understand it at this point. 03:20.930 --> 03:24.490 We've got over 24 hours to go over the material. 03:25.010 --> 03:27.210 The first let me introduce variables. 03:27.490 --> 03:30.290 They start with a dollar followed by the name. 03:30.610 --> 03:34.890 What a coincidence that our variable is actually called name. 03:35.730 --> 03:38.290 And then we assign a value to it. 03:38.730 --> 03:41.770 Let me do a fellow coder. 03:42.090 --> 03:45.930 After every expression we need to add a semicolon. 03:46.130 --> 03:48.210 This is extremely important. 03:48.530 --> 03:52.090 You need to do it after every expression in PHP. 03:53.050 --> 03:55.890 Then let's set some message. 03:56.690 --> 03:58.530 Maybe something motivational. 03:58.570 --> 04:06.040 The best way to predict the future is to create it. 04:08.800 --> 04:10.480 And the semicolon at the end. 04:10.760 --> 04:12.160 Let's fix the typo. 04:13.480 --> 04:16.440 And now let's just put it on the screen. 04:16.440 --> 04:19.760 You do it using the echo statement. 04:20.560 --> 04:24.240 So let's just say hello to our fellow coder. 04:24.960 --> 04:26.120 So I say hello. 04:26.880 --> 04:28.440 This is just a static text. 04:28.440 --> 04:37.080 But here I'm just going to put the value of the variable which would be the name and a new line character. 04:39.720 --> 04:50.200 Next up, let me add another new line character and then say here is your fault for today. 04:52.600 --> 04:53.960 Semicolon at the end. 04:59.760 --> 05:02.040 And now the actual message. 05:04.200 --> 05:09.400 And let's also add some separators at the end. 05:09.440 --> 05:11.000 At the beginning. 05:12.200 --> 05:12.760 Right, guys? 05:12.760 --> 05:14.120 We are ready to run this. 05:14.320 --> 05:16.560 As I've said this is super simple. 05:16.960 --> 05:20.560 We can open the terminal inside Visual Studio Code. 05:20.720 --> 05:21.800 This should be fine. 05:22.080 --> 05:27.040 And the way we run PHP programs is we type PHP and the program name. 05:27.760 --> 05:30.480 This is first dot PHP in our case. 05:31.120 --> 05:33.880 And this is our output. 05:35.000 --> 05:44.600 So we can fix some things like add a new line here and right here and try it again. 05:45.880 --> 05:48.000 I think it is much nicer. 05:49.320 --> 05:52.520 Maybe also a new line after the message itself. 05:52.960 --> 05:55.240 So it really looks great right now. 05:56.800 --> 06:00.440 So guys, you created your first PHP program. 06:00.440 --> 06:02.190 I think that's pretty awesome. 06:02.190 --> 06:03.550 And congratulations. 06:04.070 --> 06:10.390 So next up in the course we're going to have around six hours of similar exercises. 06:10.390 --> 06:14.750 That's gonna teach you the essentials of the PHP programming language. 06:15.230 --> 06:21.190 This is for someone who never programmed at all and never programmed in PHP. 06:21.990 --> 06:27.990 And then next up you are going to build four small, tiny projects that will teach you the essentials 06:27.990 --> 06:34.230 of how PHP interacts with the web like forums, query parameters, sessions, and cookies. 06:34.550 --> 06:38.950 And then we're going to build your first real project, the Guest Book. 06:39.070 --> 06:41.790 We're going to create our own tiny framework. 06:42.110 --> 06:44.790 So a set of reusable code. 06:44.950 --> 06:48.550 But this one won't use object oriented programming only. 06:48.710 --> 06:57.270 The second project, a blog with user sign in and admin panel, will use object oriented programming. 06:57.310 --> 07:02.420 We're gonna create our own custom framework similar to Torre, Laravel. 07:03.340 --> 07:04.460 Okay, one last thing. 07:04.460 --> 07:13.020 Before we get going under every video, you will find a link to GitHub with all the source code for 07:13.260 --> 07:14.380 that lesson. 07:14.380 --> 07:21.980 If you get stuck, it's there, use it, compare your code with mine and figure out what's different. 07:22.180 --> 07:23.860 It's the best way to learn. 07:24.420 --> 07:27.540 Also, the very next lesson is just a text page. 07:27.540 --> 07:33.340 I've dumped all the important links for the whole course there the projects, docs, everything, the 07:33.340 --> 07:35.780 code editor, and all the links. 07:36.020 --> 07:37.740 So it's all in the one place. 07:38.460 --> 07:39.020 Okay guys. 07:39.060 --> 07:39.860 That's it. 07:39.900 --> 07:40.980 No more talking. 07:41.300 --> 07:43.060 Let's start writing some code. 07:43.620 --> 07:52.180 Next up in the course, we actually have a short 15 minute primer on the theory behind PHP. 07:52.500 --> 07:54.980 You are free to skip that if you'd like. 07:55.140 --> 07:57.460 And then we're focusing on learning. 07:59.660 --> 08:02.220 So see each other in the next videos.
