我想把这个多维数组中的 [fup] => '' 都删掉，应该怎么写？？
回复讨论(解决方案)
是删掉所有的 fup 项吗？递归呀！$ar = 你的数组;foo($ar);function foo(&$ar) { foreach($ar as &$r) { if(isset($r['fup'])) unset($r['fup']); if(isset($r['s'])) foo($r['s']); }}

我是菜鸟，php是自学，所以递归这些还没写会
是的，删除所有的，fup项，我刚测试下为什么执行呢，什么结果都没有，那我要返回删除后的完整数组应该怎么写？
谢谢大神，试出来了
你打印出来看呀！你主贴中的不是你打印出来的吗？
