PHP PDO事务提交mysql语句

Jun 23, 2016 pm 02:39 PM

$db = new PDO ( 'mysql:host=' . $cfg ['hostanme'] . ';dbname=' . $cfg ['dbname'], $cfg ['username'], $cfg ['password'] );		$db->exec ( "set character_set_client = utf8" );		$db->exec ( "SET character_set_results =utf8" );		$db->exec ( "SET character_set_connection = utf8" );				$db->query ( "BEGIN" ); // 事务开始				$calories ="sa阿萨德";		$sth = $db->prepare(' INSERT INTO `test_user`  values ( null,1, :calories);');		$sth->execute(array(':calories' => $calories ));				$sths = $db->prepare(' INSERT INTO `test_users`  values ( null,1, :calories);');		$sths->execute(array(':calories' => $calories )); //故意写错的				$lastid = $db->lastInsertId();						$sd = $sth->rowCount();

想问一下,通过这种方式处理事务,是不是每次只能执行一条sql,然后在判断? 如果我SQL语句很多,例如10条以上,那不是要写10多个,判断10多次? 有没有一次可以执行多条sql的事务? 另外,mysql 中,存储过程怎么写事务?PHP如何调用?

DROP PROCEDURE IF EXISTS pro_rep_shadow_rs;create procedure pro_rep_shadow_rs(out rtn int)   begin       -- 如果出现异常,会自动处理并rollback    declare exit handler for  sqlexception ROLLBACK ;     		           -- 启动事务       start transaction;       insert into test_user values(NULL,1,'啊是大三的');		insert into test_user VALUES(NULL,23,'sdsd',ss); --故意写错的           -- 运行没有异常,提交事务       commit;       -- 设置返回值为1      set rtn=1;   end;   
Copy after login

最终还是使用存储过程来执行事务,要方便的多

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.
