Merge two different array data in one array php - php

Question

I want to merge two different array data in one array, but i'm confuse how to use array_push in this case.
this is example of my data input:
["author"]=>
array(2) {
[0]=>
string(1) "John"
[1]=>
string(1) "Doe"
}
["title"]=>
array(2) {
[0]=>
string(1) "book a"
[1]=>
string(1) "book b"
}
And the result in one array that i mean, like this:
["books"]=>
array(2) {
[0] =>
array(2) {
["author"]=>
string(1) "John"
["title"]=>
string(1) "book a"
}
[1] =>
array(2) {
["author"]=>
string(1) "Doe"
["title"]=>
string(1) "book b"
}
}
I already try using this way but it just return 1 from each array:
$data['books'] = [];
array_push($data['books'], [
'author' => $data['author'],
'title' => $data['title']
]);
if (isset($data['books'])) {
foreach ($data['books'] as $k => $v) {
$data['books'][$k]['author'] = (int)$v['author'];
$data['books'][$k]['title'] = (int)$v['title'];
}
}
result:
["books"]=>
array(1) {
[0]=>
array(2) {
["author"]=>
int(1)
["title"]=>
int(1)
}
}

You have to transpose your arrays with the keys in mind.
function transpose(array $arr){
$transArr = [];
foreach($arr as $keyRow => $subArr) {
foreach($subArr as $keyCol => $value) {
$transArr[$keyCol][$keyRow] = $value;
}
}
return $transArr;
}
This function can be used universally for similar problems. The function comes from this class.
How to use:
$input = [
"author"=> ["John","Doe"],
"title" => ["book a","book b"],
];
$books = transpose($input);
echo '<pre>';
var_export($books);
Or if you want to use the class:
$books = tableArray::create($input)
->transpose()
->fetchAll()
;
Output:
array (
0 =>
array (
'author' => 'John',
'title' => 'book a',
),
1 =>
array (
'author' => 'Doe',
'title' => 'book b',
),
)
If "author" and "title" exist as two arrays, $ input must first be created like this:
$input = ['author' => $arrayAuthor, 'title' => $arrayTitle];
