How to rearrange an array?

Question

PHP

There is an array
$data = array(
array( 'x' => '1', 'y' => '1', 'z' => '1' ),
array( 'x' => '2', 'y ' => '2', 'z' => '2' ),
array( 'x' => '3', 'y' => '3', 'z' => '3' ),
array( ' x' => '4', 'y' => '4', 'z' => '4' )
);
You need to regroup in the form:
$data = array(
'x' => array('1', ..., '99'),
'y' => array('1', ..., '99'),
'z' => array('1', ..., '99')
);
I'm thinking of doing something like this:

$result = array();
foreach($data as $val){
  foreach($val as $key => $type)
    for ($i=0; $i < count($type); ++$i) {
    $result = array($i => $type);
    }
   }

But as usual it doesn't work.

Answer 1

$result = array();
foreach($data as $val) {
    foreach($val as $key => $type) {
        $result[$key][] = $type;
    }
}

Answer 2

Come on, by the third question, will you already learn how to format the code with normal formatting?
And this. As long as you are stuffed with ready-made codes, this "as usual does not work" for you will remain so.
Did not try to look at the result of the work of your hands and redo the code?
why don't you add anything to $result?
