A hash::combine array - cakephp

Question

I have this array from a sql query :
[0] => Array
(
[T1] => Array
(
[First] => A
[Second] => Apples
[LastChild] => F
)
[0] => Array
(
[LastChildNb] => 23
)
)
I would like to have this result :
[0] => Array
(
[0] => Array
(
[First] => A
[Second] => Apples
[LastChild] => F
[LastChildNb] => 23
)
)
How do I do this ? I think I should use "hash::combine", but what would the code be ?

Answer 1

You could do something like this, with $arr being your array above:
$arr = array_reduce($arr, function(&$arr, $v) {
return array_merge($arr, (array) $v);
}, array());

Answer 2

You can do
array_merge($arr[0]['T1'], $arr[0][0])
Where $arr is defined as follows:
$arr = [0 => Array
(
'T1' => Array
(
'First' => 'A',
'Second' => 'Apples',
'LastChild' => 'F'
),
0 => Array
(
'LastChildNb' => 23
)
)];
For multiple records in $arr, you can simply cycle over all records and do this merge manually.
However, assuming you're getting the array as a result of a find() method, I suggest you consider using T1__LastChildNb as an alias within the 'fields' of your condition. Simply said, if you have a find like following:
$this->T1->find('all', ['fields' => 'T1.*, (SOME SUBQUERY) AS LastChildNb']);
then modifying it to be
$this->T1->find('all', ['fields' => 'T1.*, (SOME SUBQUERY) AS T1__LastChildNb']);
might be what you're looking for since it will return desired array directly (tested on 2.6).
Let me know if you're interested in more information.
