WEBVTT 00:00.620 --> 00:04.280 I'll call you back again to another video lecture in PHP. 00:04.280 --> 00:09.620 And in this video lecture I'll go ahead and teach you about do while loop. 00:15.080 --> 00:20.870 As I said in the previous lecture, we discussed about a while loop. 00:20.870 --> 00:25.160 And in this video lecture we're going to talk about do while loop. 00:25.370 --> 00:28.610 Now this is what we did in the previous lecture. 00:28.610 --> 00:30.980 We actually did this. 00:30.980 --> 00:34.340 And when you run this code it gives you this. 00:34.640 --> 00:42.800 What is defined between while loop and do while loop is that in while loop we always check the condition 00:42.800 --> 00:47.150 which is this before we execute and go back and check the condition. 00:47.150 --> 00:52.520 But in do while loop, we first of all execute the program before we check the condition. 00:52.610 --> 00:57.860 Then go ahead and say that this is 11 and that 11 is less than ten. 00:57.890 --> 01:03.170 If I run this code, you see, I don't have anything like 11 right in here. 01:03.200 --> 01:10.280 Now do while loop is go ahead and take this white condition out of this white condition and I'm going 01:10.310 --> 01:12.440 to place it right in here. 01:13.220 --> 01:20.720 So that is the while loop and then put a semicolon at the end and this place removed the while loop. 01:20.750 --> 01:25.160 I'll go ahead and put do and then I'll go ahead and save. 01:25.760 --> 01:32.870 So if I run this program 11, we first of all we printed out the body will be printed out before we 01:32.870 --> 01:34.610 go ahead to check the condition. 01:34.640 --> 01:37.220 Now let's go ahead and run this code and check it out. 01:37.880 --> 01:42.710 11 so it has executed is 11 and nothing again happened. 01:42.740 --> 01:49.490 The reason is because in the while loop we first of all is the body before checking for the condition. 01:49.520 --> 01:56.590 Now if I go back here and put this to be equal to one and save this and run this code and have 1 to 01:56.590 --> 01:59.240 10, one was actually printed out. 01:59.270 --> 02:05.330 Then it goes and check the condition and came back to print out the other ones. 02:05.330 --> 02:09.590 So this is the difference between while loop and do while loop. 02:09.590 --> 02:13.220 So I hope that is clear and is very straightforward. 02:13.220 --> 02:15.050 So go ahead and put it on your own. 02:15.050 --> 02:16.550 Check it out, play around with it. 02:16.550 --> 02:22.190 And if you have any questions on this, please go ahead and use the question and answer section. 02:22.190 --> 02:24.830 And I'm going to get back to you as soon as possible. 02:24.860 --> 02:25.820 Thank you so much. 02:25.820 --> 02:28.760 And I'm going to see you in the next video lecture.
