$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对比操作
变成
$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");
怎么写
先说明下
$aa=array("id"=>"1","time"=>"5","neirong"=>"www");这个数据之所已没有是因为 $aa和$bb时间是一样的
$aa=array("id"=>"2","time"=>"55","neirong"=>"www");
$bb=array("id"=>"2","time"=>"50");
那是因为bbdetime比aa得time小所以。。
$cc=array("id"=>"3","neirong"=>"delete");对应的$aa不存在所以。。
$cc=array("id"=>"4","time"=>"555","neirong"=>"www");
$cc=array("id"=>"5","time"=>"555","neirong"=>"www");
因为$bb没有对应的id 4和5的数据。。所以
太基础了，回去重练...

有本事你写个？ 多维数组拼写起来确实费点时间，试着写了一个，不知道是不是楼主所要的结果

你原始的数据只有 $bb=array("id"=>"3","time"=>"555");
我不能凭空臆造出 "neirong"=>"delete"
但你可以，因为规则是你制定的
你自己加上就是了

刚看版主的代码是最好的 直接遍历$aa跟$bb对比修改<?php$aa = array( array("id"=>"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
