Question

How to display an element from the last array dynamically in PHP.
For example:

Array ( [0] => Array ( [id] => 6 [user_id] => 8 [category_path] => Sport)
        [1] => Array ( [id] => 8 [user_id] => 8 [category_path] => Computers))

in order to return the “id” from the last array

8

And for the next example

Array ( [0] => Array ( [id] => 6 [user_id] => 8 [category_path] => Sport)
        [1] => Array ( [id] => 8 [user_id] => 5 [category_path] => Computers)
        [2] => Array ( [id] => 16 [user_id] => 45 [category_path] => Soft))

in order to return

   16

Thank you!
