请问php二维数组 查找相同的值合并 如何写？

Question

array(2) {
  [0] => array(5) {
    ["picTitle"] => string(33) "标题1"
    ["picCategroy"] => string(6) "分类"
    ["picAuthor"] => string(12) "作者"
    ["picPostTime"] => string(19) "2014-11-20 16:05:16"
    ["pictureurl"] => string(55) "attachment/picture/uploadify/20141120/546da0784831c.png,attachment/picture/uploadify/20141120/546da0746edb8.png"
  }}
就是这样的 相同的标题 不同的就是pictureurl
合并就行了 求版主指点~

$ar = array(
  array(
    "picTitle" => "标题1",
    "picCategroy" => "分类",
    "picAuthor" => "作者",
    "picPostTime" => "2014-11-20 16:05:16",
    "pictureurl" => "attachment/picture/uploadify/20141120/546da0784831c.png",
  ),
  array(
    "picTitle" => "标题1",
    "picCategroy" => "分类",
    "picAuthor" => "作者",

    "pictureurl" => "attachment/picture/uploadify/20141120/546da0746edb8.png",
  ),
);
foreach(call_user_func_array('array_merge_recursive', $ar) as $key=>$item) {
  $res[$key] = join(',', array_unique($item));
}
var_export($res);
array (

)

Answer 2

版主大人 还得麻烦您看眼 这个是在相同的标题下才合并的 貌似有点复杂
array(6) {
  [0] => array(5) {
    ["picTitle"] => string(7) "标题2"
    ["picCategroy"] => string(6) "海报"
    ["picAuthor"] => string(12) "星耀学园"
    ["picPostTime"] => string(19) "2014-11-26 11:59:50"
    ["pictureurl"] => string(55) "attachment/picture/uploadify/20141126/547550278b7db.jpg"
  }
  [1] => array(5) {
    ["picTitle"] => string(7) "标题2"
    ["picCategroy"] => string(6) "海报"
    ["picAuthor"] => string(12) "星耀学园"
    ["picPostTime"] => string(19) "2014-11-26 11:59:50"
    ["pictureurl"] => string(55) "attachment/picture/uploadify/20141126/54755027ab89b.jpg"
  }
  [2] => array(5) {
    ["picTitle"] => string(7) "标题2"
    ["picCategroy"] => string(6) "海报"
    ["picAuthor"] => string(12) "星耀学园"
    ["picPostTime"] => string(19) "2014-11-26 11:59:50"
    ["pictureurl"] => string(55) "attachment/picture/uploadify/20141126/547550273b753.jpg"
  }
  [3] => array(5) {
    ["picTitle"] => string(7) "标题2"
    ["picCategroy"] => string(6) "海报"
    ["picAuthor"] => string(12) "星耀学园"
    ["picPostTime"] => string(19) "2014-11-26 11:59:50"
    ["pictureurl"] => string(55) "attachment/picture/uploadify/20141126/54755027d8488.jpg"
  }
  [4] => array(5) {
    ["picTitle"] => string(33) "同步写入信息和附件表里"
    ["picCategroy"] => string(6) "海报"
    ["picAuthor"] => string(12) "星耀学园"
    ["picPostTime"] => string(19) "2014-11-20 16:05:16"
    ["pictureurl"] => string(55) "attachment/picture/uploadify/20141120/546da0746edb8.png"
  }
  [5] => array(5) {
    ["picTitle"] => string(33) "同步写入信息和附件表里"
    ["picCategroy"] => string(6) "海报"
    ["picAuthor"] => string(12) "星耀学园"
    ["picPostTime"] => string(19) "2014-11-20 16:05:16"
    ["pictureurl"] => string(55) "attachment/picture/uploadify/20141120/546da0784831c.png"
  }
}
用您这个处理完 都合并在一起了 我想是不同的标题的是不一样的 标题1 相同标题的都合并在一起 一个数组 标题2相同的合并在一起一个数组 就是图片链接pictureurl 这个进行合并  求大大指点 如何判断很多个标题里 判断标题是重复的呢 这个肯定是一个标题有多个重复的数组， 主要是区分去多个不同标题。 
array ( 'picTitle' => '标题2,同步写入信息和附件表里', 'picCategroy' => '海报', 'picAuthor' => '星耀学园', 'picPostTime' => '2014-11-26 11:59:50,2014-11-20 16:05:16', 'pictureurl' => 'attachment/picture/uploadify/20141126/547550278b7db.jpg,attachment/picture/uploadify/20141126/54755027ab89b.jpg,attachment/picture/uploadify/20141126/547550273b753.jpg,attachment/picture/uploadify/20141126/54755027d8488.jpg,attachment/picture/uploadify/20141120/546da0746edb8.png,attachment/picture/uploadify/20141120/546da0784831c.png', )

Answer 4

随便写了下，没测试过，大楷是这么个思路$ar = array(
  array(
    "picTitle" => "标题1",
    "picCategroy" => "分类",
    "picAuthor" => "作者",
    "picPostTime" => "2014-11-20 16:05:16",
    "pictureurl" => "attachment/picture/uploadify/20141120/546da0784831c.png",
  ),
  array(
    "picTitle" => "标题1",
    "picCategroy" => "分类",
    "picAuthor" => "作者",
    "picPostTime" => "2014-11-20 16:05:16",
    "pictureurl" => "attachment/picture/uploadify/20141120/546da0746edb8.png",
  ),
);//标题=>数组索引数组
$map_arr=array();
foreach($ar as $key=>$item)
{
//判断是否在标题=>数组索引数组中
if(isset($map_arr[$item['picTitle']]))
{
//在的话合并
$ar[$key]=array_merge($ar[$key],$map_arr[$item['picTitle']]);
}
else
{
//不在的话存入映射索引
$map_arr[$item['picTitle']]=$item;
unset($ar[$key]); //删除原来在数组存在的值
}
}

Answer 5

补充下  unset($ar[$key]); //删除原来在数组存在的值
这句移动到这个下面，疏忽写错了
//在的话合并
$ar[$key]=array_merge($ar[$key],$map_arr[$item['picTitle']]);

Answer 6

$arr = array(
  array(
    "picTitle" => "标题1",
    "picCategroy" => "分类",
    "picAuthor" => "作者",
    "picPostTime" => "2014-11-20 16:05:16",
    "pictureurl" => "attachment/picture/uploadify/20141120/546da0784831c.png",
  ),
  array(
    "picTitle" => "标题1",
    "picCategroy" => "分类",
    "picAuthor" => "作者",
    "picPostTime" => "2014-11-20 16:05:16",
    "pictureurl" => "attachment/picture/uploadify/20141120/546da0746edb8.png",
  )
);
$item=array();
foreach($arr as $key=>$value){
    foreach($value as $k=>$v){
        if(!isset($item[$k])){
            $item[$k]=$v;
        }
    }
}
print_r($item);

谢谢版主大人 解决了 只不过最后的这个var_export函数去掉 就是我要的结果了~
