Time Narration
00:00 The basic principle of for loops is that it will repeat a block of codes the number of times you specify, using not only a condition but also the initialization in the beginning and the increment at the end.
00:18 So how much you want to increment your variable determines the number of times your variable loops by.
00:38 So, it is a bit more complex to write. However it looks good , it does the job and its very compact.
00:43 Now we write 'for'
00:53 so you have got three parts of your code here,and your block and that is all you need and your content can go here.
01:03 So, I am going to say 'echo' here and let's create a variable 'num'. So, we have echoed out 'num'.
01:13 In here, we write num =1, not = = 1 because we are setting the variable num to the value of 1.
01:22 Then we have a condition. For eg, while num < = to 10
01:31 Then, we have the increment values. So, we are going to have num ++ and the loop is done.
01:37 So, we type 'For', and our variable num=1
01:47 Then we have our condition 'While num< =10, the loop will continue, and then we have num ++
01:52 As you can see this is much more useful than having num ++ down below .
01:55 and we need not declare this up here.
01:59 It can be declared inside these parentheses.
02:02 O.K., I forgot the line-break.
02:07 I’ll add a line break on to the end of this.
02:10 Refresh.
02:12 There you go.
02:17 You've got your loop ten times.
02:25 And as it has been specified in such a way it will loop only when num is less than or equal to 10.
02:28 After that the loop will break and you may continue with the rest of the script.
02:36 This is a bit more complex but once you learn the basics you will find it a lot easier .
02:37 Thanks for watching.
