問個二位元組操作問題

$aa=array("id"=>"1","time"=>"5","neirong"=>"www");
$aa=array("id"=>"2","time"=>"55","neirong"=>"www");
$aa=array("id"=>"4","time"=>"555","neirong"=>"www");
$aa=array("id"=>"5","time"=>"555","neirong"=>"www");
$aaa=array("duibi"=>$aa);

$bb=array("id"=>"1","time"=>"5");
$bb=array("id"=>"2","time"=>"50");
$bb=array("id"=>"3","time"=>"555");
$bbb=array("duibi"=>$bb);

$aaa和$bbb對比操作
變成
$cc=array("id"=>"2","time"=>"55","neirong"=>"www");
$cc=array("id"=>"3","neirong"=>"delete");
$cc=array("id"=>"4","time"=>"555","neirong"=>"www");
$cc=array("id"=>"5","time"=>"555","neirong"=>"www");

怎麼寫



先說明下

$aa=array("id"=>"1","time"=>"5","neirong"=>"www");這個資料之所已沒有是因為 $aa和$bb時間是一樣的

$aa=array("id"=>"2","time"=>"55","neirong"=>"www");
$bb=array("id"=>"2","time"=>"50");
那是因為bbdetime比aa得time小所以。。

$cc=array("id"=>"3","neirong"=>"delete");對應的$aa不存在所以。。


$cc=array("id"=>"4","time"=>"555","neirong"=>"www");
$cc=array("id"=>"5","time"=>"555","neirong"=>"www");

因為$bb沒有對應的id 4和5的資料。。所以

回複討論(解決方案)

太基礎了，回去重練...

有本事你寫個？

多維陣列拼字起來確實費點時間，試著寫了一個，不知道是不是樓主所要的結果

不對哈 沒delete

[id] => 3
[neirong] => delete

你原始的資料只有 $bb=array("id"=>"3","time"=>"555");
我不能憑空臆造出 "neirong"=>"delete"
但你可以，因為規則是你制定的
你自己加上就是了

我這個太麻煩了，自己可以改改，不太擅長簡化代碼

哈哈我剛加上了

我這個太麻煩了，自己可以改改，不太擅長簡化代碼

剛看版主的代碼是最好的 直接遍曆$aa跟$bb對比修改

"1","time"=>"5","neirong"=>"www"),  array("id"=>"2","time"=>"55","neirong"=>"www"),  array("id"=>"4","time"=>"555","neirong"=>"www"),  array("id"=>"5","time"=>"555","neirong"=>"www"),); $bb = array(  array("id"=>"1","time"=>"5"),  array("id"=>"2","time"=>"50"),  array("id"=>"3","time"=>"555"),); foreach($aa as $v) $r[$v['id']] = $v;foreach($bb as $v) {  $k = $v['id'];  if(! isset($r[$k]))  {    $v['content']='delete';    $r[$k] = $v;  }   elseif($r[$k]['time'] < $v['time']) $r[$k] = $v;  elseif($r[$k]['time'] == $v['time']) unset($r[$k]);}ksort($r);print_r($r);?>s
