如何刪除多維陣列中指定元素?

  [0] => Array        (            [v] => 1            [fup] => 0            [n] => 伺服器            [s] => Array                (                    [0] => Array                        (                            [v] => 2                            [fup] => 2                            [n] => one                            [s] => Array                                (                                    [0] => Array                                        (                                            [v] => 3                                            [fup] => 41                                            [n] => one                                        )                                    [1] => Array                                        (                                            [v] => 4                                            [fup] => 1                                            [n] => two                                        )                                    [2] => Array                                        (                                            [v] => 5                                            [fup] => 1                                            [n] => three                                        )                                )                        )                    [1] => Array                        (                            [v] => 42                            [fup] => 2                            [n] => two                            [s] => Array                                (                                    [0] => Array                                        (                                            [v] => 73                                            [fup] => 42                                            [n] => one                                        )                                    [1] => Array                                        (                                            [v] => 74                                            [fup] => 42                                            [n] => two                                        )                                    [2] => Array                                        (                                            [v] => 75                                            [fup] => 42                                            [n] => three                                        )                                )                        )                    [2] => Array                        (                            [v] => 43                            [fup] => 2                            [n] => three                        )                )        )

我想把這個多維陣列中的 [fup] => '' 都刪掉，應該怎麼寫？？

回複討論(解決方案)

是刪掉所有的 fup 項嗎？遞迴呀！

$ar = 你的數組;foo($ar);function foo(&$ar) {  foreach($ar as &$r) {     if(isset($r['fup'])) unset($r['fup']);     if(isset($r['s'])) foo($r['s']);  }}

我是菜鳥，php是自學，所以遞迴這些還沒寫會
是的，刪除所有的，fup項，我剛測試下為什麼執行呢，什麼結果都沒有，那我要返回刪除後的完整數組應該怎麼寫？

謝謝大神，試出來了

你列印出來看呀！你主貼中的不是你列印出來的嗎？
