在PHP中PDO解决中文乱码问题的一些补充
前两天了解了一下PDO连接数据库的相关资料,配置相关在网路上都有很多相关资料,我在这里说说解决中文乱码显示问题
我的环境是appsver包,
在网上最常出现的解决中文乱码显示的代码是:
第一种:PDO::__construct($dsn, $user, $pass, array
(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES'utf8';"));
我试过用第一种方法,可结果是,name字段只显示一个‘C'字符。之后的本该显示中文的地方却是空白。
结果是这样的:如图1示
第二种:PDO::__construct($dsn, $user, $pass);
PDO::exec("SET NAMES 'utf8';");
第二种我也在我的环境里测试过,显示效果如图1所示,碰到这种情况,香港虚拟主机,把utf8替换成GBK,就能显
示了。另外,这里的PDO::在使用的时候用$pdo->代替,当然,这个是个变量,变量名称可以自己定义。
第三种:$pdo->query('set names utf8;');
至于第三种呢,看了上面两种,应该也知道要吧utf8替换成GBK,也能正确显示了。
这几种我都测试过了。都行。哈哈。另外,我在这里还介绍一种解决中文乱码的一种方法,不过大同小异,
基本和第三种没什么却别,香港服务器,不通的是,这种方法,没用query而是用exec,代码如下:
$pdo->exec("SET CHARACTER SET GBK");
呵呵。怎么样啊,这四种方法我都亲自试过了。 ,香港空间
