Array help

[jasondavis]

Array 1=
If I get an array of FRIEND_ID numbers

Array 2=
and an array of BULLETIN_ID numbers and somehow in this array the USER_ID of the user who created it

Can I take the list from array 1 and find all matches from array2 where the FRIEND-ID in array 1 matches the userid in array 2 and have the result make a new array?

IF this is possible I am lost as how to do it

A mix of [man]array_walk/man and [man]array_search[/man] could do it... but if they had the same keys, you could use something like array_intersect. Although you may be able to get away with array_intersect depending upon how you have your array set up.
