求教: 下面的数组我该如何生成~!
$traffic_type $in_bytes
18 2011110
19 1999110
18 1923832
19 2893823
其中$traffic_type不只有18和19,种类数不确定,
上面有很多行那样的数据。我想生成如下数组:
{
{18:{{"value"=>"2011110"},{"value"=>"1923832"}}
{19:{{"value"=>"1999110"},{"value"=>"2893823"}}
}
上面数组可能写得不对,不过大概就是这么个意思。
在while循环里面应该怎么生成上面的数组?
whlie(){$arr_data_by_prote.$traffic_type[] = array("value"=>$in_bytes);$arr.$traffic_type[] = array("value"=>$in_bytes);}
这样吗? 不过这样报错了。
回复讨论(解决方案)
whlie(){ $arr[] = array($traffic_type=>array()); $arr.$traffic_type[] = array("value"=>$in_bytes);}
上面我自己的代码是这个。
whlie($row=...){
$arr[$row['traffic_type']][] = array("value"=>$row['in_bytes']);
}
whlie($row=...){
$arr[$row['traffic_type']][] = array("value"=>$row['in_bytes']);
}

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.
