数据库数据调用问题
表 business_circle
字段 id name parent_id
1 朝阳 0
2 昌平 0
3 大望路 1
4 呼家楼 1
5 朝阳公园 1
$sql1 = mysql_query("select * from business_circle order by id asc");
while($rs1 = mysql_fetch_assoc($sql1)){
echo $rs1['name'].$rs1['parent_id'].'
';
}
调出的结果是
大望路 1
呼家楼 1
朝阳公园 1
parent_id就是父类的id
我想调出的结果是
大望路 朝阳
呼家楼 朝阳
朝阳公园 朝阳
完整代码应当怎么写,高手帮忙下,直接给完整代码,谢谢
回复讨论(解决方案)
$rs = mysql_query("select.name, b.name as pname from business_circle a, business_circle b where a.parent_id = b.id");while($row = mysql_fetch_assoc($rs)) { echo $row['name'] . ' ' . $row['pname'] . '<br>';}
楼上 的大哥谢谢了,但调不出来,显示空白
大神写错了点地方.帮忙补上.

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,

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.

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

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.
