|Hello and welcome. I have decided to create seperate tutorials for each looping statement.

|-
|0:07
|I want to keep it simple. This will be useful as a reference also if you need to refer to how a particular loop works.

|-
|0:17
|In this tutorial, we will learn about the WHILE loop

|-
|0:21
|A WHILE loop checks for a condition at the start at the loop and executes the code depending on whether this condition is True or not

|-
|0:38
|for example I'll start my 'WHILE loop' here and this is the condition and this is my block.

|-
|0:51
|I'll represent my block between curly brackets.

|-
|0:56
|My condition is here. Now, in the 'IF statement', for example I used 1==1.

|-
|1:04
|Now if I say 'test' or 'loop' here.

|-
|1:07
|This is a loop here and then a break. Now what happens is as long as 1=1, it would create a loop

|-
|1:17
|If I do something here, lets try this.

|-
|1:22
|It would probably crash your browser because the loop would be repeated as long as 1=1 and for infinite no. of times, 1 will always equal 1.

|-
|1:34
|So since the loop will always be repeated, your browser will crash.

|-
|1:40
|Lets say while a variable, 'num' is smaller or equal to 10 and under echo i can say - 'num ++'

|-
|1:57
| '++' is an arithmetical operator. And what it basically does is, it increases num by 1. It is the same as writing 'num =num +1'

|-
|2:16
|So it takes num and says that it is equal to the value of num plus 1.

|-
|2:23
|So this again is an arithmetical operator. What's going to happen is -
|-
|2:29
|We are going to say 'num' lesser than or equal to '10', if yes then echo loop and then say add 1 on to the variable num

|-
|2:41
|But what we should really do is create 'num = 1' at the moment. So loop once at 1. This will then equal 2 then 3 then 4 all the way up to 10 and then it will stop
|-
|3:01
|After that the rest of the code below this will continue.

|-
|3:06
|So we said this 1 and see what will we get. Okay we got a loop 1,2,3,4,5,6,7,8,9,10 times

|-
|3:20
|Now to make it more fun I'll say loop 1 and I'll concatenate 'num' to the end of that

|-
|3:27
|In fact let's make it simpler and say 'num' inside - it will make it much easier to read

|-
|3:37
|Okay I'll say loop 1 and add 1 and then I'll say loop 2 and I'll add another 1; that's loop 3 add another 1 up to 10.

|-
|3:49
|Lets open this up. Refresh it. There you go. You got loop 1,2,3 all the way up to 10 as you can see

|-
|3:58
|Lets change this value here to 100. Refresh that. You can see it has gone to hundred. The bigger the number, the longer it will take to loop

|-
|4:08
|Let's take 6000. Let's refresh that. It's going to take a while. There you go - up to 6000. So it's very efficient in this way

|-
|4:20
|You can try combining this with an 'array' to create a program that echoes out of the alphabet inside the 'array'

|-
|4:27
|You can use loops to echo out every single value of an array

|-
|4:32
|Just give it a go. I will probably do this in one my tutorial - not in the basics section though

|-
|4:40
|However, this is the basics structure. What I also recommend you to do is create a variable here called 'max' and put your maximum value here

|-
|4:53
|This will do exactly the same thing. It's just a lot more easy to read and you can declare all this here and this would be a reference to it

|-
|5:03
|If you have more than 1 loop. I prefer it for readability and flexibility for my program. Okay so that's a WHILE loop. Let me summarise. It checks the condition of the start

|-
|5:17
|If the condition is True. it would execute this block of code and you can do things like 'echo alpha'

|-
|5:24
|Your variable is being incremented. Make sure that you do increment your variable otherwise it will loop for infinity.

|-
|5:32
|Thanks for watching. This is Sidharth for the Spoken Tutorial Project, signing off. Goodbye.
