Question

I want to loop from 1 till 5. That’s easy if you use a for loop:

for ($i=1; $i<=5; $i++)
{
 // do something
}

But imagine instead of starting by $i=1 I have a random start number from 1 to 5 and this time its value is 3. So I have to start looping from 3 and the loop sequence should be: 3,4,5,1,2

I already have the radom number, let’s say it is 3, then I need 3 4 5 1 2 .. if it was 5, I would be needing 5 1 2 3 4

How can I do this??

Thanks a lot!

Answer 1

Try this :

for ($i = 0, $j = 3; $i < 5; $i++)
{
   echo $j;
   $j %= 5;
   $j++;
}

You need two vars to do what you want. If you set J = 3, it’ll do 3 4 5 1 2

have fun.
