Answer 1

I believe this is returning the desired output?
$arr=array(
0 => array(
'OPEN' => 'understanding',
'HAPPY' => 'great',
'ALIVE' => 'playful',
'GOOD' => 'calm'
),
1 => array(
'OPEN' => 'confident',
'HAPPY' => 'gay',
'ALIVE' => 'courageous',
'GOOD' => 'peaceful'
),
2 => array(
'OPEN' => 'reliable',
'HAPPY' => 'joyous',
'ALIVE' => 'energetic',
'GOOD' => 'at ease'
)
);
$output=array();
$keys=array_keys( $arr[0] );
for( $i=0; $i < count( $arr ); $i++ ){
foreach( $keys as $key )$output[$key][]=$arr[$i][$key];
}
echo '<pre>', print_r($output,true), '</pre>';
The result:
Array
(
[OPEN] => Array
(
[0] => understanding
[1] => confident
[2] => reliable
)
[HAPPY] => Array
(
[0] => great
[1] => gay
[2] => joyous
)
[ALIVE] => Array
(
[0] => playful
[1] => courageous
[2] => energetic
)
[GOOD] => Array
(
[0] => calm
[1] => peaceful
[2] => at ease
)
)

Answer 2

If I don't understood your requirement then this solution will work for you.I used the array_column() approach because your current code with for() and foreach() loop seems little bit messy.
$arr=array(
0 => array(
'OPEN' => 'understanding',
'HAPPY' => 'great',
'ALIVE' => 'playful',
'GOOD' => 'calm'
),
1 => array(
'OPEN' => 'confident',
'HAPPY' => 'gay',
'ALIVE' => 'courageous',
'GOOD' => 'peaceful'
),
2 => array(
'OPEN' => 'reliable',
'HAPPY' => 'joyous',
'ALIVE' => 'energetic',
'GOOD' => 'at ease'
));
$expected = [];
$keys = array_keys($arr[0]);
foreach($keys as $key){
$expected[$key] = array_column($arr,$key);
}
print '<pre>';
print_r($expected);
print '</pre>';
Output:
Array
(
[OPEN] => Array
(
[0] => understanding
[1] => confident
[2] => reliable
)
[HAPPY] => Array
(
[0] => great
[1] => gay
[2] => joyous
)
[ALIVE] => Array
(
[0] => playful
[1] => courageous
[2] => energetic
)
[GOOD] => Array
(
[0] => calm
[1] => peaceful
[2] => at ease
)
)
