Because number of items in 2 sub-arrays is always equal, you can use a for loop like this:
$array = [
0 => [
0 => [
'url' => 'https://domain.com.vn',
'value' => 'Keyword B3'
],
1 => [
'url' => 'https://domain.com.vn',
'value' => '[IMAGES 1]'
]
],
1 => [
0 => [
'url' => 'https://domain-4.com.vn',
'value' => 'D1'
],
1 => [
'url' => 'https://domain-4.com.vn',
'value' => 'E3'
]
]
];
$result = [];
for ($i = 0 ; $i < count($array[0]); $i++) {
$result[] = [
'url' => [$array[0][$i]['url'], $array[1][$i]['url']],
'value' => [$array[0][$i]['value'], $array[1][$i]['value']],
];
}
print_r($result);
Result:
Array
(
[0] => Array
(
[url] => Array
(
[0] => https://domain.com.vn
[1] => https://domain-4.com.vn
)
[value] => Array
(
[0] => Keyword B3
[1] => D1
)
)
[1] => Array
(
[url] => Array
(
[0] => https://domain.com.vn
[1] => https://domain-4.com.vn
)
[value] => Array
(
[0] => [IMAGES 1]
[1] => E3
)
)
)
For a dynamic solution, you will need to iterate the first level of the array, then combine the first deep subarray's keys with the return value ofarray_map()'s special transposing behavior withnull and the spread operator.
It sure is a bunch of voodoo, but it is dynamic.
Code: (Demo) (Demo showing different length first level data sets)
var_export(
array_map(
function ($subarray) {
return array_combine(
array_keys($subarray[0]),
array_map(null, ...array_values($subarray))
);
},
$array
)
);
