Can't get my Hash::combine right in CakePHP - php

Question

I have an array that I'm trying to remodel with Hash::combine.
This is my array
Array
(
[0] => Array
(
[T1] => Array
(
[second] => APPLES
[Color] => GREEN
[Color_en] => #99cc66
[nombre] => 56
)
)
[1] => Array
(
[T1] => Array
(
[second] => APPLES
[Color] => BLUE
[Color_en] => #0099ff
[nombre] => 678
)
)
[2] => Array
(
[T1] => Array
(
[second] => BANANAS
[Color] => GREEN
[Color_en] => #99cc66
[nombre] => 366
)
)
[3] => Array
(
[T1] => Array
(
[second] => BANANAS
[Color] => BLUE
[Color_en] => #0099ff
[nombre] => 2000
)
)
)
And what I want to achieve is the array below :
Array
(
[0] => Array
(
[0] => Array
(
[y] => 56
[color] => #99cc66
)
[1] => Array
(
[y] => 678
[color] => #0099ff
)
)
)
[1] => Array
(
[0] => Array
(
[y] => 366
[color] => #99cc66
)
[1] => Array
(
[y] => 2000
[color] => #0099ff
)
)
)
So first array is "APPLES" and second is "BANANAS", "y" is "nombre and "Color_en" becomes "color".
I've tried so many different ways with Hash::combine but I'm out of ideas how tho do this.

Answer 1

This is outside the scope of Hash::combine(). You can't use it to rename array indices.
The closest thing you could probably do is combine the array values by {n}.T1.second to group the fruits together like this:-
Hash::combine($array, '{n}.T1.nombre', '{n}.T1', '{n}.T1.second');
For what you are trying to achieve you will need to rebuild the array yourself using a foreach loop. Something like this:-
$data = [];
foreach ($array as $value) {
$data[$value['T1']['second']][] = [
'y' => $value['T1']['nombre'],
'color' => $value['T1']['Color_en']
];
}
