WEBVTT 00:00.530 --> 00:00.770 I will. 00:00.770 --> 00:08.030 Going back again to the end of the lecture in p p and in this video lecture we go ahead and look at 00:08.030 --> 00:10.790 uh, HTML and PHP. 00:17.420 --> 00:17.900 All right. 00:17.900 --> 00:20.480 So we're going to look at uh HTML and PHP. 00:20.480 --> 00:26.510 And then we go ahead and learn about how to use HTML in PHP. 00:26.840 --> 00:27.410 All right. 00:27.410 --> 00:34.460 So you can see that our when I actually printed out this we were able to print out Hello World. 00:34.460 --> 00:40.760 And if we go ahead on the inspect element of view the page source, this guy had a view page source. 00:40.760 --> 00:44.930 You can see that this is a HTML page. 00:44.930 --> 00:49.640 And right in here we can see our PHP code printed out. 00:49.670 --> 00:50.360 Hello world. 00:50.360 --> 00:56.480 And there is nothing like PHP and we can be able to write some HTML code right inside this PHP. 00:56.630 --> 01:02.060 And it can be used to execute that as a HTML file and not a PHP file. 01:02.090 --> 01:03.950 So is that actually possible? 01:03.950 --> 01:05.540 Yes, it is possible. 01:05.540 --> 01:07.200 So how is that possible? 01:07.230 --> 01:08.640 Let's go ahead and close this. 01:08.670 --> 01:09.720 But before, go ahead. 01:09.720 --> 01:17.730 To start this, I want to show you how this actually works for each time we, uh, run this on our server. 01:18.840 --> 01:24.060 So this is our server, which we actually used. 01:24.060 --> 01:28.740 And then remember that this server is always open until you finish everything you are doing. 01:28.740 --> 01:33.300 So anytime you are running your program, your server must always be open for you to run PHP. 01:33.360 --> 01:38.850 And you can see that it has some things like accept close, accept close, accept close. 01:38.850 --> 01:42.690 So each time you run this code, it's going to generate some of these figures. 01:42.690 --> 01:49.230 What actually happens is that PHP is actually, uh, being run and the server is actually working at 01:49.230 --> 01:49.920 the same time. 01:49.920 --> 01:52.110 Now I'm going to write some things here. 01:52.140 --> 01:56.760 Then we're going to run the code, we're going to check our server and know if actually there's some 01:56.760 --> 01:58.620 things working going on in the background. 01:58.620 --> 02:00.660 So this does not actually concern us. 02:00.690 --> 02:01.860 It's not our problem. 02:01.860 --> 02:03.360 We don't actually need it. 02:03.390 --> 02:07.710 We just want to make sure to know if our server is actually running very well. 02:07.740 --> 02:14.310 Now, for us to be able to write PHP and very well, we're going to learn about H2O. 02:14.310 --> 02:18.060 Just like I told you, you have to know a bit about HTML, right? 02:18.090 --> 02:21.510 So we are not actually learning HTML as to start afresh. 02:21.510 --> 02:27.810 We're going to write some HTML code right inside this PHP and it's going to execute that. 02:27.840 --> 02:34.830 Then go ahead and check our page source and know if that actually prints out the HTML code. 02:34.860 --> 02:37.920 Now we actually wrote Hello World. 02:37.920 --> 02:45.540 And what if I go right inside this hello world and make that to give that a heading tag of H1. 02:45.540 --> 02:50.550 And then let's go over here and call this uh h1. 02:50.580 --> 02:56.070 Now if you go ahead and run this, let's go over here and refresh this. 02:56.100 --> 02:58.860 You can see that this is Hello World. 02:58.860 --> 03:02.640 And you can see that it actually enlarged this. 03:02.670 --> 03:06.420 Now if I go ahead and check the pixels go ahead and view the page source. 03:06.420 --> 03:08.940 You can see we have H1 right in here. 03:08.940 --> 03:12.300 But previously it was actually Hello World. 03:12.300 --> 03:18.150 And because this HTML tag is right in here PHP recognizes HTML tag. 03:18.150 --> 03:20.170 That is very, very important. 03:20.200 --> 03:27.820 Let's go ahead and put someone at once and go ahead and say a call and uh, go ahead and uh, create 03:27.850 --> 03:29.710 a line right in here. 03:30.520 --> 03:34.510 And uh, go ahead and press semicolon at the end because you must actually do that. 03:34.510 --> 03:38.620 So go ahead and say echo again to print out anything. 03:38.620 --> 03:43.090 So anytime you want to print out anything with HTML, uh, anytime. 03:43.090 --> 03:46.810 Want to print out anything in PHP, you're going to use the word echo. 03:46.810 --> 03:50.950 So let's go ahead and put the paragraph tag and check this paragraph tag. 03:50.950 --> 03:58.240 So inside this paragraph tag I'm going to say welcome to PHP. 03:58.480 --> 03:58.960 All right. 03:58.960 --> 04:00.340 So go ahead and create a tag. 04:00.340 --> 04:06.040 And we're going to run this code save this code and uh go back here and uh run this. 04:06.040 --> 04:11.830 So now you can see I have Hello World and you can see the line which is h r which we created. 04:11.830 --> 04:14.710 And welcome to PHP is right in here. 04:14.740 --> 04:17.560 Now let's go ahead and inspect this element and check it out. 04:17.560 --> 04:19.540 So we. 04:19.570 --> 04:20.110 Okay. 04:20.140 --> 04:25.670 This is actually uh view page source and not inspection of element. 04:25.700 --> 04:28.790 I just want to see the back end and what is actually going on. 04:28.820 --> 04:30.080 So I'm viewing the pitch source. 04:30.110 --> 04:30.530 This guy. 04:30.530 --> 04:31.460 Let's check it out. 04:31.610 --> 04:35.450 So now you can see we have this red in here. 04:36.140 --> 04:39.680 I want to drag this up so it can be used to show more. 04:39.710 --> 04:43.760 It says demo the body right in here and you can see hello world. 04:43.790 --> 04:46.100 The hash one is here. 04:46.100 --> 04:48.380 And this is our line tag. 04:48.380 --> 04:50.240 And this is our paragraph tag. 04:50.240 --> 04:52.700 And we're going to PHP right inside there. 04:52.700 --> 04:56.450 So you can see that it was able to give us what is inside hello world. 04:56.450 --> 04:57.890 And it was able to give us. 04:57.920 --> 04:59.000 Welcome to PHP. 04:59.120 --> 05:03.380 And it was able to recognize the HTML tags. 05:03.380 --> 05:08.300 So you can actually write HTML tags right inside your PHP code. 05:08.300 --> 05:10.730 And the PHP will actually honor that. 05:10.730 --> 05:19.340 And it will go ahead and, uh, you know, execute your programs while obeying the HTML tags. 05:19.370 --> 05:19.910 All right. 05:19.940 --> 05:23.630 So now I'm going to show you our command prompt. 05:23.630 --> 05:25.370 This is our server run on the back end. 05:25.400 --> 05:31.850 You can see that the more we are running this code, the more this is being actually, Um, do some 05:31.880 --> 05:32.780 work on the back end. 05:32.810 --> 05:33.590 Let's go back here. 05:33.590 --> 05:37.250 And I'm going to run this code while keeping this right in here. 05:37.250 --> 05:38.510 So I'm going to run this code. 05:38.510 --> 05:42.290 So let's go ahead and check it out and see if actually anything works at the back end. 05:42.320 --> 05:43.760 So go ahead and refresh this. 05:43.760 --> 05:49.760 And for each time I refresh it you can see that it's being uh is accepted. 05:49.760 --> 05:53.720 And it's go over to the file and gets whatever is there. 05:53.720 --> 05:55.640 You can see the get command is here. 05:55.640 --> 05:57.230 It gets whatever is in the file. 05:57.260 --> 05:59.390 Go ahead and run this code again. 05:59.420 --> 06:02.750 You can see it gets whatever it is in the file. 06:02.780 --> 06:05.510 WW slash sites dot PHP. 06:05.510 --> 06:07.130 And that is really very cool. 06:07.130 --> 06:13.790 So when you are working uh, as a PHP developer, you actually know that your server is working and 06:13.790 --> 06:17.210 back end and making sure that everything is going well. 06:17.240 --> 06:17.690 All right. 06:17.690 --> 06:23.780 So I went ahead and did the code for you go ahead and practice this and put it on your own, check it 06:23.780 --> 06:28.370 out and try out the HTML or talks and make sure everything works fine. 06:28.370 --> 06:33.200 And if you have any questions, use the question and answer section and I'm going to get back to you 06:33.200 --> 06:34.130 as soon as possible. 06:34.160 --> 06:34.700 Thank you. 06:34.700 --> 06:37.190 And I'm going to see you in the next video lecture.
