Question

I need to write some code using some for-loops which tests the values of some array data.

1st pass: checking the following…

{x0,y0}

2nd pass: checking the 4 bits of data…

{x0,y0}, {x1,y0}, 
{x0,y1}, {x1,y1}.

3rd pass: checking 9 bits of data…

{x0,y0}, {x1,y0}, {x2,y0}, 
{x0,y1}, {x1,y1}, {x2,y1},
{x0,y2}, {x1,y2}, {x2,y2}.

My little brain doesn’t seem to want to function to get this answered. Can anyone help?

Answer 1

<?php

for ($pass = 0; $pass < count($matrix); $pass++)
{
    for ($i = 0; $i <= $pass; $i++)
    {
        for ($j = 0; $j <= $pass; $j++)
        {
            checkbit($matrix[$i][$j]);
        }
    }   
}

?>

Maybe something like this?
