PHP PDO 调用存储过程 返回多个集合 和 输出参数 如何获取?
select * from table;
select * from table1;
out $id;
如上:存储过程返回两个结果集和一个输出参数,如何在PHP中获得这两个结果集和输出参数?
回复讨论(解决方案)
一个个读取
见 PDOStatement::nextRowset 方法说明

如果只有多个集合我知道,但是有输出参数,如下
$stmt = $db->prepare("CALL pro_test(:name,@sp_result);"); $stmt->execute (array(':name'=>$name)); $outputArray = $db->query("select @sp_result")->fetch(PDO::FETCH_ASSOC); print_r($outputArray["@sp_result"]);
存储过程返回一个集合,输出参数需要查询一次,但是到了这一步就出错了
$outputArray = $db->query("select @sp_result")->fetch(PDO::FETCH_ASSOC);
Error: SOAP-ENV:Server, string: Call to a member function fetch() on a non-object
我猜应该是之前存储过程返回了个结果,再查一个就出错了,如何解决?
这是手册上的示例
$sql = 'CALL multiple_rowsets()';$stmt = $conn->query($sql);$i = 1;do { $rowset = $stmt->fetchAll(PDO_FETCH_NUM); if ($rowset) { //想想这里为什么要先判断一下 printResultSet($rowset, $i); } $i++;} while ($stmt->nextRowset());

你可能理解错我的意思了,我需要存储过程的结果集和存储过程返回的参数,不过已经解决了,还是去官网看的,谢谢关注,·· 后面还有很多问题
Note for MySQL: to use input/output parameters for stored procedures with PDO use PDO.Query() statement. For example: <?php $dbh->query("CAST SomeStoredProcedure($someInParameter1, $someInParameter2, @someOutParameter)"); $dbh->query("SELECT @someOutParameter"); ?> Or, if you want very much to use PDO.Prepare(), insert "SELECT @someOutParameter" in your stored procedure and then use: <?php $stmt = $dbh->prepare("CAST SomeStoredProcedure(?, ?)"); $stmt ->execute(array($someInParameter1, $someInParameter2)); ?>

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 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.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
