PHP Array - Unpivot - Invert Matrix Key Value

Sometimes for some reason can there be the need to "UNPIVOT" a multidimensional array. That switch
:

Array (

[0] => Array
(
[first] => 1
[second] => 2
[third] => 3
[fourth] => 4
)

[1] => Array
(
[first] => 5
[second] => 6
[third] => 7
[fourth] => 8
)

[2] =>
Array (
[first] => 9
[second] => 10
[third] => 11
[fourth] => 12
)

)

to

Array (

[first] => Array
(
[0 ] => 1
[1] => 5
[2] => 9
)

[second] => Array
(
[0] => 2
[1] => 6
[2] => 10
)

[third] => Array
(
[0] => 3
[1] => 7
[2] => 11
)

[fourth] => Array
(
[0] => 4
[1] => 8
[2] => 12
)

)

All thanks to the following function:
<br /> <?php<br /> $ arrayTot = Array (<br /> Array ('first' => 1, 'second' => 2, 'third' => 3, 'fourth' => 4), <br /> Array ('first' => 5, 'according to '=> 6,' third '=> 7,' fourth '=> 8), <br /> Array (' first '=> 9,' seconds' => 10, 'third' => 11, 'fourth' => 12 ) <br />) <br /> echo '<pre>'; <br /> print_r($arrayTot); <br /> echo ' </pre> '; <br /> <br /> echo '*********************************************'; <br /> <br /> echo ' <pre> '; <br /> print_r(TransposeArray($arrayTot)); <br /> echo ' </pre> '; <br /> <br /> function TransposeArray($in_array) <br /> { <br /> $out_array = Array(); <br /> $m = 0; <br /> for ($i = 0; $i < count($in_array); $i++,$m++) <br /> { <br /> foreach(array_keys($in_array[$i]) as $key_val) <br /> { <br /> $out_array[$key_val][$m] = $in_array[$i][$key_val]; <br /> } <br /> } <br /> return $out_array; <br /> <br />}?> <br />
