array:
A-B-C-D-E-F
J is the son of C. update array so:
A-B-C-J-D-E-F
how do I insert J after C in the array?
I also map the array in a loop (array of comments for display). Will this method take a very long time to perform?

You can use array_splice() with $length set to 0.

Example:
$arr_alphabet = array('a', 'b', 'd');
array_splice($arr_alphabet, 2, 0, 'c');
// $arr_alphabet is now: array('a', 'b', 'c', 'd');
