How do I delete a specified element in a multidimensional array?

  [0] = = Array ([v] = 1 [Fup] = 0 [n] = = Server [s] + A                            Rray ([0] = = Array ([v] = 2 [Fup] = 2 [n] = one [s] + Arra                                        Y ([0] = = Array                                            ([v] = 3 [fup] = 41                                    [n] = one)                                            [1] = = Array ([v] = 4                                    [Fup] = 1 [n] =    ) [2] = = Array (                                            [v] + 5 [fup] = 1                        [n] = three))                            ) [1] = = Array ([v] = 42                                [Fup] = 2 [n] = [s] = = Array                                            ([0] = = Array (                                            [v] [fup] = 42 [n] = one) [1] = A                    Rray                    ([v] = 74 [                                    FUP] = [n] =                                            [2] = = Array ( [v] = [fup] = [n] =                    > three))) [2] = = Array ([v] = [fup] = > 2 [n] = three)))

I want to delete this multi-dimensional array [fup] = ", how should I write??

Reply to discussion (solution)

Is it to erase all the fup? Recursion, yes!

$ar = your array, foo ($ar), function foo (& $ar) {  foreach ($ar as & $r) {     if (isset ($r [' fup '])) unset ($r [' fup ']); C2/>if (Isset ($r [' s])) foo ($r [' s ']);}  }

I am a rookie, PHP is self-taught, so recursive these have not written will
Yes, delete all, fup items, I just tested why do it, what results are not, then I want to return the complete array after deletion how should I write?

Thank you, big God, for trying.

You print it out and look! Didn't you print it on your main post?
