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:

<&#63;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;

    }

  }

&#63;>

Copy after login

(2)在实例化 PDO 的第四个参数添加 MYSQL_ATTR_INIT_COMMAND 属性:

        $_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;

    }

  }

&#63;>
