PDO connect does not work

Question

I try connect to mysql DB with PDO, but does not work. i write:

 $db = new PDO('mysql:dbname=test;host=localhost','user','pass');

returns error:

 Warning: PDO::__construct() [pdo.--construct]: [2002] No connection could be made because
 the target machine actively refused it.

please tell me , wath the PDO wants to?

phpversion: 5.3.9

host: local computer, (server - "usbwebserver")

Answer 1

It's a port problem. USBwebsever uses mysql port 3307 instead of 3306, so use $db = new PDO('mysql:dbname=test;host=localhost:3307','user','pass');
