I want to work with PDO, through PHP command line. It works perfect through the PHP web API, but not through the command line.

But when I execute the command: php test.php, it says unknown class PDO.

I think it has something to do with the thread-safety difference. Because, when I execute the above command, the following warnings come: -

F:\shema\htdocs>php test.php

PHP Fatal error:  Class 'PDO' not found in F:\shema\htdocs\test.php on line 2

• PHP version: 5.2.9-2, downloaded from here.
• OS: Windows Vista

If the problem is with the modules, where do I get the thread safe modules for those modules?
