请大神帮忙 php二维数组重新排序
Array ( Array ('id' => 3, 'username' => 'alex ','parentname'=> 'john'
,'proname' => 'tttt' 'num'=> 1 , 'userid' =>6 ,'parentid'=>8 ,
'cpid'=> 0 ,'mobile'=> 15533336666 ,'parentmobile' => 156477765465) );
把最后两个分别放在第2个和第4个位置 ,怎么重新排序?

'userid' =>6 ,'parentid'=>8 ,'cpid'=> 0 );
回复讨论(解决方案)
你这算什么排序?
不就是调一下位置吗?为什么要调呢?
最后要用excel输出呀,不这样排序的话,格式全乱了
从数据库里面调出100条的话,有无这样的排序办法?

从数据库?你查询的时候直接改变下顺序不就行了?

最后两个字段还是从另外的表间接查询的结果,然后用数组追加进来的,所以就导致现在的这个位置问题
1、从数据库里取出时,不要简单的 select *
而是 select id, username, mobile .... 这样一一开列,你要求的排列顺序不就有了
2、用 php 代码也是可以的
$a = Array ( Array ('id' => 3, 'username' => 'alex ','parentname'=> 'john' ,'proname' => 'tttt', 'num'=> 1 , 'userid' =>6 ,'parentid'=>8 , 'cpid'=> 0 ,'mobile'=> 15533336666 ,'parentmobile' => 156477765465) );$k = Array ('id', 'username', 'mobile', 'parentname', 'parentmobile', 'proname', 'num', 'userid', 'parentid', 'cpid');foreach($a as $i=>$v) { extract($v); $a[$i] = compact($k);}print_r($a);
Array( [0] => Array ( [id] => 3 [username] => alex [mobile] => 15533336666 [parentname] => john [parentmobile] => 156477765465 [proname] => tttt [num] => 1 [userid] => 6 [parentid] => 8 [cpid] => 0 ))
你的是key=>value
怎么排都不影响使用。
不过可以这样写
<?php$arr = array( array('id'=>3,'username'=>'alex','parentname'=>'john','proname'=>'tttt','num'=> 1 , 'userid' =>6 ,'parentid'=>8 ,'cpid'=> 0 ,'mobile'=> 15533336666 ,'parentmobile' => 156477765465), array('id'=>3,'username'=>'alex','parentname'=>'john','proname'=>'tttt','num'=> 1 , 'userid' =>6 ,'parentid'=>8 ,'cpid'=> 0 ,'mobile'=> 15533336666 ,'parentmobile' => 156477765465), array('id'=>3,'username'=>'alex','parentname'=>'john','proname'=>'tttt','num'=> 1 , 'userid' =>6 ,'parentid'=>8 ,'cpid'=> 0 ,'mobile'=> 15533336666 ,'parentmobile' => 156477765465),);$result = array();$fields = array('id','username','mobile','parentname','parentmobile','proname','num','userid','parentid','cpid');foreach($arr as $k=>$v){ $tmp = array(); foreach($fields as $f){ $tmp[$f] = $v[$f]; } $result[] = $tmp;}print_r($result);

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,

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.
