PHP使用PDO操作数据库的乱码问题解决方法,pdo乱码
本文实例讲述了PHP使用PDO操作数据库的乱码问题解决方法。分享给大家供大家参考,具体如下:
当使用 PDO 连接操作数据库的时候,有时会出现:保存在数据库中的汉字为乱码。以文件为 UTF-8 格式,其解决方法如下:
(1)实例化的对象直接执行 query() 方法或者 exec() 方法:
<?php class DB { static public function getDB() { try { $_opts_values = array(PDO::ATTR_PERSISTENT=>true,PDO::ATTR_ERRMODE=>2); $_pdo = new PDO(DB_DSN, DB_NAME, DB_PASS, $_opts_values); } catch (PDOException $e) { exit('数据库连接错误!错误信息:'.$e->getMessage()); } $_pdo->query("SET NAMES utf8"); // $_pdo->exec('SET NAMES utf8'); //设置数据库编码,两种方法都可以 return $_pdo; } } ?>
(2)在实例化 PDO 的第四个参数添加 MYSQL_ATTR_INIT_COMMAND 属性:
<?php class DB { static public function getDB() { try { $_opts_values = array(PDO::ATTR_PERSISTENT=>true,PDO::ATTR_ERRMODE=>2,PDO::MYSQL_ATTR_INIT_COMMAND=>'SET NAMES utf8'); $_pdo = new PDO(DB_DSN, DB_NAME, DB_PASS, $_opts_values); } catch (PDOException $e) { exit('数据库连接错误!错误信息:'.$e->getMessage()); } return $_pdo; } } ?>
注:以上方法,都经过测试。

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,

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.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.
