Hey fellow php'ers i have a slight problem: I have 2 arrays that look sort of like this: Array => [0] Array( [id]=434b5g6 [unique_id]=banana [level]=8 [quality]=2) [1] Array( [id]=bfrfnr [unique_id]=apple [level]=4 [quality]=1) [2] Array( [id]=yt347509 [unique_id]=grapefruit [level]=8 [quality]=2 ) [3] Array( [id]=456645 [unique_id]=strawberry [level]=1 [quality]=6) Array => [0] Array( [id]=434b5g6 [unique_id]=strawberry [level]=8 [quality]=2) [1] Array( [id]=bfrfnr [unique_id]=apple [level]=4 [quality]=1) [2] Array( [id]=yt347509 [unique_id]=grapefruit [level]=8 [quality]=2 ) [3] Array( [id]=456645 [unique_id]=pinapple [level]=1 [quality]=6) I need a way to remove the elements in which the [unique_id] exists in both arrays so that im left with 2 arrays which only contain elements that are unique. Eg if we were to run the script on these 2 arrays i would be left with: Array => [0] Array( [id]=434b5g6 [unique_id]=banana [level]=8 [quality]=2) Array => [0] Array( [id]=456645 [unique_id]=pinapple [level]=1 [quality]=6) Im really not sure how to do this though, i know there is array_diff but this only works for single level arrays. Im using a multi level one and only trageting the [unique_id] part of it. Any help would be really appreciated.
Why not create a seperate array, loop all the array's you can and check if the unique id is not in the seperate array, if not, add it, if it exists then remove it! And even with array_diff you can do it, but its just a little more work! maby its a great idea to swap the id and unique id's? then you always have a `unique` unique_id
