Transpose a PHP multidimensional array with predefined keys

Question

I have a multidimensional array with 3 keys (\"length\", \"width\" and \"height). Each key is associated with an array of values:

$data = [
    \"length\" =>          


        

Answer 1

The following function will do the job:

function transpose($data)
{
    $result = [];
    $keys = array_keys($data);
    for ($row = 0,  $rows = count(reset($data)); $row < $rows; $row++) {
        foreach ($keys as $key) {
            $result[$row][$key] = $data[$key][$row];
        }
    } 

    return $result;
}

Notice that the function is a general solution it doesn’t depend on the name of the keys nor on the number of entries of each key.

Answer 2

you can try this one to get the arrays like you said

   $height = array(12,44);
$width = array(20,50);
$length = array(30,50);
$new_array[0] = $height[0];
$new_array[1] = $width[0];
$new_array[2] = $length[0];
$new_array2 = $new_array[1];
print_r($new_array);
echo "<br>";
print_r($new_array2);
