My English is weak but I want to share my code.
I want to change formation of array but when I use null is callback function in array_map().
It has problem in result so I write new small function for it.
<?php
function array_change_formation($arr=array()) {
$new_arr = array();
foreach($arr as $k => $v)
foreach($v as $k2 => $v2)
$new_arr[$k2][$k] = $v[$k2];
return $new_arr;
}
?>
Input:
Array
(
[Human] => Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 4
)
[Pet] => Array
(
[0] => Cat
[1] => Dog
[2] => Rabbit
[3] => Rat
)
)
OutPut:
Array
(
[0] => Array
(
[Human] => 1
[Pet] => Cat
)
[1] => Array
(
[Human] => 2
[Pet] => Dog
)
[2] => Array
(
[Human] => 3
[Pet] => Rabbit
)
[3] => Array
(
[Human] => 4
[Pet] => Rat
)
)
I hope it can useful.
