Changes between Version 2 and Version 3 of Ticket #36590, comment 9

v2	v3
5	5	''EDIT NOTE: We don't have to worry about the replace part in this case. All key values should be unique (otherwise the normal post would'nt work either)''
6	6

9	9	Also, the current function does the array merge on the whole $_POST value. I can imagine with larger menu's this can get slower than to do this merge/replace on the first array key that is found. The code has a lot less to loop through for every new key that is found.
