How to merge arrays by key?

Question

PHP

I have a two dimensional array:

$users = [
    'name' => ['John', 'George', 'Tom'],
    'age' => [32, 25, 44],
];

You need to get an array like this:

$users = [
    ['name' => 'John', 'age' => 32],
    ['name' => 'George',  'age' => 25],
    ['name' => 'Tom', 'age' => 44],
];

So far the only code that comes to mind is:

$keys = array_keys($users);
$result = [];

$size = count($users['name']);

for ($i=0; $i < $size; $i++) {
    $row= [];

    foreach ($keys as $key) {
        $row[$key] = $users[$key][$i];
    }

     $result[] = $row;
}

Thanks

Your array is an MxN matrix and you just need to rotate it 90 degrees.
To save the keys, we go not for, but foreach.
In the end it will turn out like this.

$output = [];
foreach ($users as $y => $values) {
    foreach ($values as $x => $value) {
        $output[$x][$y] = $value;
    }
}
