请问php二维数组 查找相同的值合并 如何写？
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
1 | array(2) {<br /> [0] => array(5) {<br /> ["picTitle"] => string(33) "标题1"<br /> ["picCategroy"] => string(6) "分类"<br /> ["picAuthor"] => string(12) "作者"<br /> ["picPostTime"] => string(19) "2014-11-20 16:05:16"<br /> ["pictureurl"] => string(55) "attachment/picture/uploadify/20141120/546da0784831c.png"<br /> }<br /> [1] => array(5) {<br /> ["picTitle"] => string(33) "标题1"<br /> ["picCategroy"] => string(6) "分类"<br /> ["picAuthor"] => string(12) "作者"<br /> ["picPostTime"] => string(19) "2014-11-20 16:05:16"<br /> ["pictureurl"] => string(55) "attachment/picture/uploadify/20141120/546da0746edb8.png"<br /> }<br />}

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[$key]); //删除原来在数组存在的值
}
}
------解决思路----------------------1 | <br />$arr = array(<br /> array(<br /> "picTitle" => "标题1",<br /> "picCategroy" => "分类",<br /> "picAuthor" => "作者",<br /> "picPostTime" => "2014-11-20 16:05:16",<br /> "pictureurl" => "attachment/picture/uploadify/20141120/546da0784831c.png",<br /> ),<br /> array(<br /> "picTitle" => "标题1",<br /> "picCategroy" => "分类",<br /> "picAuthor" => "作者",<br /> "picPostTime" => "2014-11-20 16:05:16",<br /> "pictureurl" => "attachment/picture/uploadify/20141120/546da0746edb8.png",<br /> )<br />);<br />$item=array();<br />foreach($arr as $key=>$value){<br /> foreach($value as $k=>$v){<br /> if(!isset($item[$k])){<br /> $item[$k]=$v;<br /> }<br /> }<br />}<br />print_r($item);<br />
