I have an array like mentioned below, which I want to rearrange without using loop:
Array
(
[0] => Array
(
[Books] => Array
(
[id] => 4
)
)
[1] => Array
(
[Books] => Array
(
[id] => 3
)
)
[2] => Array
(
[Books] => Array
(
[id] => 2
)
)
[3] => Array
(
[Books] => Array
(
[id] => 1
)
)
)
I want an output like this:
Array(4,3,2,1)
