I'm having a lil problem here.
For example, theres this sequence here..
$sequence = 1234567890;
For arrays right, the number "1" will be in position 0, "2" will be in position 1 and so on..
So, as you can see I'm going to make it to reading frames so it'll be like this.

First reading frame: 1234567890
Second reading frame: 234567890
Third reading frame: 34567890

How do i make it to second reading frame by using an array? i can only display it using substring:
$frame2 = substr($sequence, 1);
which is wrong as the "2" in "234567890" will still be in position 1.. instead of 0 (which is what i want).So basically, i want the second reading frame in an array with the number "2" in position 0. And for the third reading frame, the number "3" also in position 0. How is that possible?

Thanks!
