Transposing multidimensional arrays in PHP

I have three arrays:

$a = (a1, a2, a3);
$b = (b1, b2, b3);
$c = (c1, c2, c3);

I want to combine these arrays to create:

$newa = (a1, b1, c1);
$newb = (a2, b2, c2);
$newc = (a3, b3, c3);

Answer 1

I changed things a little. I didn't use $newA, #newB, $newC, but used a $m array instead.

    $a = array( "a1", "a2", "a3");
    $b = array( "b1", "b2", "b3");
    $c = array( "c1", "c2", "c3");

$count = count($a);
$i = 0;
$m = array();
for($i;$i < $count; $i++) {
        $m[] = array( $a[$i], $b[$i], $c[$i]);
}

print_r($m);

Outputs:

Array
(
    [0] => Array
        (
            [0] => a1
            [1] => b1
            [2] => c1
        )

    [1] => Array
        (
            [0] => a2
            [1] => b2
            [2] => c2
        )

    [2] => Array
        (
            [0] => a3
            [1] => b3
            [2] => c3
        )
