这个是数组
主要功能就是thinkphp视图模型里查询的结果 我想
查询每个数组里的相同的标题值 然后进行合并 合并数组 貌似用array_merge()
我怎么查找相同的标题呢 foreach 遍历 返回数组里的索引值 可以么 貌似 key() 函数有这个功能 求好心人具体写个
相同的标题 数组元素的位置 这样返回 合并的时候就直接 这样的形式用 可以么
array_merge(array[0],array[1])
相同的标题 然后合并的是图片的连接字段这样 pictureurl就是这个不一样
简单说就是多图上传 发文章这样的 文章找找以后要是有几千篇 那数组就是好几倍的量 高效的计算 能用的 求大神指点啊~
这样
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 } [1] => 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/20141120/546da0746edb8.png }}
回复讨论(解决方案) 那你最终要达成什么样的结果呢？
目的不同，算法也不同

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~

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。

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(

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[$key]); //删除原来在数组存在的值
}
}
补充下 unset($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']]);

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~
