    replied to How to bubble sort 2d array?
    in PHP
    Seems like me and Deizi share the same assignments. Yes, it is necessary to bubble sort it as a whole.
    I`ve already done it the easy way - foreach to create a 1d array out of the 2d, then bubble sort, than array_chunk to make it 2d again.
    Now I`m trying to do it without changing it.
    Here is what I have so far :
    Code:
    $array = [
		[5, 8, 7, 6],
		[1, 15, 10, 9],
		[2, 13, 3, 4],
		[11, 16, 12, 14],
    ...

        Oh, God! Yes, now I see it, thank you so much! All I had to do is add a reset line before the inner loop... Thank you, thank you, thank you!

          Yes, I have tried this too...Both with a for and a foreach loop. But this way I get the sum of all elements (136). I can`t figure out what I`m missing, so that I can get the sum of every single row and col of the matrix.

            I`m actually trying to solve the same problem. I have some kind of a solution, I get the right answers, but it`s quite lame by my opinion... I`m sure there is a better (and shorter!!!) way :/

            Code:
            include_once 'readline.php';

$array = array(
	array(1, 2, 3, 4),
		array(5, 6, 7, 8),
		array(9, 10, 11, 12),
		array(13, 14, 15, 16),
);

$rows = 4;
$cols = 4;

$sum = 0;
            ...
