php5 pdo新改动加载注意事项_php技巧

pdo php5 load

前面的#号去了,但是加载不了,仔细一看,哦,原来还有个
extension=php_pdo.dll
于是,就OK了

顺便说下,不要再把ext下的dll文件拷到windows目录下了,在环境变量里把php的路径加进去就行了,这样好点。是吧?

原来的中文问题是这样解决
在查询之前
mysql_query("set names 'utf8'");
而用了pdo后 

复制代码 代码如下:

$dbh = new PDO($dsn, $user, $pass); //初始化一个PDO对象,就是创建了数据库连接对象$dbh
echo "连接成功
";
//你还可以进行一次搜索操作
$dbh->query("set names utf8");//就这样。。。

5 记住:字符集一定要统一,数据库的,网站的。页面的
