Answer 1

This should do the job:
<?php
$order = [
'city' => 0,
'name' => 1,
'country' => 2,
'address' => 3,
'lastname' => 4,
'number' => 5,
];
$data = [
[
'name' => 'Haroldas',
'number' => '444',
'address' => 'g.',
'city' => 'eee',
'country' => 'f',
'lastname' => 'r',
],
[
'name' => 'Lukas',
'number' => '999',
'address' => 'rrr',
'city' => 'ttt',
'country' => 3,
'lastname' => 'r',
],
];
foreach ($data as &$entry) {
uksort($entry, function ($a, $b) use ($order) {
return strcmp($order[$a], $order[$b]);
});
}
print_r($data);
The output is:
Array
(
[0] => Array
(
[city] => eee
[name] => Haroldas
[country] => f
[address] => g.
[lastname] => r
[number] => 444
)
[1] => Array
(
[city] => ttt
[name] => Lukas
[country] => 3
[address] => rrr
[lastname] => r
[number] => 999
)
)

If you want to reorder that use foreach then create a new array.
$arrReorder = [];
foreach($yourArr as $key => $val){
$arrReorder[] = ['city' => $val['city'], 'name' => $val['name'], 'country' => $val['country'], 'address' => $val['address'], 'lastname' => $val['lastname'], 'number' => $val['number'] ];
}
print_r($arrReorder);
