在PHP中交换（扭曲）多维数组

Question

i want to "twist" a 2d array by "90°"..

let me explain that.

I have an array like this:

array(
    array( adam , brad , chris , david ),
    array( 21   , 23   , 22    , 26    )
)

and i want to convert that into something like this:

array(
    array( adam  , 21 ),
    array( brad  , 23 ),
    array( chris , 22 ),
    array( david , 26 )
)

how can i do that ?

Answer 1

Something like this should work:

// Your array stored as $arr

$newArr = array();
for ($i = 0;$i < count($arr[0]); $i++) {
    $newArr[] = array($arr[0][$i],$arr[1][$i]);
}

EDIT: You tag sorting, but the array is already sorted, do you want sorting too?
