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
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

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

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
How does session hijacking work and how can you mitigate it in PHP?
Apr 06, 2025 am 12:02 AM
Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.
Describe the SOLID principles and how they apply to PHP development.
Apr 03, 2025 am 12:04 AM
The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
