I have an array like this:
array(
[cat] => news,
[comments_count] => 2,
[meta] => array(
[first_meta] => 44,
[second_meta] => 54,
)
)
The above code is an example of array that I have. Now I wanna make the above array clear like this:
array(
[cat] => news,
[comments_count] => 2,
[first_meta] => 44,
[second_meta] => 54,
)
(means Delete -meta- but not it's indexes. I want to add indexes of meta to the first array)
Add the meta array to the array and then unset the meta array:
$array = $array + $array['meta'];
unset($array['meta']);
You may use the below function if you have a multidimentional array and you can reuse it anywhere.
function array_flatten($array) {
if (!is_array($array)) {
return false;
}
$result = array();
foreach ($array as $key => $value) {
if (is_array($value)) {
$result = array_merge($result, array_flatten($value));
} else {
$result[$key] = $value;
}
}
return $result;
}
$array = array(
'cat' => 'news',
'comments_count' => '2',
'meta' => array(
'first_meta' => '44',
'second_meta' => '54',
)
);
var_dump(array_flatten($array));
The result will be
array(4) {
["cat"]=>
string(4) "news"
["comments_count"]=>
string(1) "2"
["first_meta"]=>
string(2) "44"
["second_meta"]=>
string(2) "54"
}
Otherwise if you just need to flatten meta array as in your question. array_merge() the meta array and unset meta it as below.
$result = array_merge($array, $array["meta"]);
unset($result["meta"]);
var_dump($result);
metaarray?
