try{ $dsn = ‘mysql:host=localhost;dbname=myblog‘; $username = ‘root‘; $passwd = ‘123456‘; $pdo = new PDO($dsn, $username, $passwd); var_dump($pdo); }catch(PDOException $e){ echo $e->getMessage(); }二、URI形式 [php] view plaincopyprint?
try{ $dsn = ‘uri:file://F:\wamp\www\myBlog\dsn.txt‘; $username = ‘root‘; $passwd = ‘123456‘; $pdo = new PDO($dsn, $username, $passwd); var_dump($pdo); }catch(PDOException $e){ echo $e->getMessage(); } //dsn.txt mysql:host=localhost;dbname=myblog三、配置文件方式 [php] view plaincopyprint?
try{ $dsn = ‘mypdo‘; $username = ‘root‘; $passwd = ‘123456‘; $pdo = new PDO($dsn, $username, $passwd); var_dump($pdo); }catch(PDOException $e){ echo $e->getMessage(); } //其中在php.ini文件的任意位置加上以下代码,并保存重启服务器 pdo.dsn.mypdo="mysql:host=localhost;dbname=myblog"
