PDO连接到本地主机（未知的mysql服务器主机）

Question

I can connect to MySQL using mysql_* functions with the same credentials.

Is there any way to connect to a local MySQL database using PDO with a user that has USAGE privilege only? I don't have opportunity to set the rights to ALL , which I've read as a solution to a similar problem here in SO.

SQLSTATE[HY000] [2005] Unknown MySQL server host 'localhost,dbname=crmdb' (74)

Answer 1

 // PDO
$pdo = new PDO("mysql:host=localhost;dbname=database", 'username', 'password');

NOTE SEMI-COLON ; NOT a COMMA ,
