How can I solve the following problem?

Fatal error: Class 'PDO' not found in C:\Inetpub\wwwroot\workplace\index.php on line 29





I'm using php 5, Dev-PHP and SQLite 3_3_8.

How can I solve the following problem?
Some sql data object class definition is not being found.


So check for a typo if none then


check your access rights and path to the data object on line 29





You know dictionary or schema paths depending on your site


implementation. When checking your paths be sure to follow access rights across any pipes (internodal channels).
