PHP - How to install PDO driver? (Windows)

Question

I am setting up PHP and MySQL (Maria DB) on Windows 8.1. I edited php.ini file and uncommented the following lines:

extension=php_mysql.dll
extension=php_mysqli.dll
extension=php_pdo_mysql.dll

But unfortunately I cannot connect to database because there are no pdo drivers shown in phpinfo output. So, when I try to establish database connection, an exception is thrown:

Fatal error: Uncaught exception 'PDOException' with message 'could not find driver'

How can this problem be solved?

Answer 1

Finaly I managed to settle this stuff. I corrected extension_dir entry (absolute file path was needed) in php.ini file and database connection began to work.

Answer 2

Check the extension_dir of your current apache directory, i installed 2 php versions and apache, and the problem was in wamp\bin\apache\Apache2.4.23\bin\php.ini , the path of ext was incorrect
