mysql“ insert 表名……”表名是否可以使变量?怎样实现?


回复讨论(解决方案)

$tableName = 'member';

mysql_query("insert into".$tableName." values ()");

$tableName = 'member';

mysql_query("insert into".$tableName." values ()");
例如,每个用户都在注册的时候同时生成了一个相应的数据表,那等一个0101的用户登录后,我把0101(既是用户名也是表名)保存到$_SESSION['msg']中,那我这样写:
$tableName=$_SESSION['msg'];
mysql_query("insert into".$tableName." (id,name,telephone) values('$counters[0]','$counters[1]','$counters[2]')");
为什么还有错误呢?

提示什么错误?

你用session之前

session_start();了?

mysql_query("insert into ".$tableName."  (id,name,telephone) values ('$counters[0]','$counters[1]','$counters[2]')");

打印你的sql,看输出什么东西

mysql_query("insert into ".$tableName."  (id,name,telephone) values ('$counters[0]','$counters[1]','$counters[2]')");
Error:You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''0101' (id,name,telephone)values('?1','王刚','19011224442 ')' at line 1
session_start();也写了

表名不用加单引号 直接输出sql语句看下就知道错在那了

打印你的sql,看输出什么东西
输出:insert into '0101' (id,name,telephone)values('?1','王刚','19011224442 ')

mysql_query("insert into `$tableName` (id,name,telephone) values ('$counters[0]','$counters[1]','$counters[2]')");
Copy after login

表名不用加单引号 直接输出sql语句看下就知道错在那了

谢谢你,按照你说的们果然调试出来了,
$tableName=$_SESSION['msg'];
$sql =mysql_query('set names utf8'); 
mysql_query($sql);
$sql="insert into $tableName (id,name,telephone)values('$counters[0]','$counters[1]','$counters[2]')";

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. 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,

Describe the SOLID principles and how they apply to PHP development. 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.

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.
