What is the difference between the nd_pdo_mysql and pdo_mysql extensions?

For some reason the pdo_mysql PHP extension, on our hosted server, fails to run a query that uses a MySQL view, with this error message.

Answer 1

To connect to your MySQL server from PHP, there are two versions of drivers:

1. mysqlnd
2. libmysql

In order to connect to your MySQL server using mysqlnd driver, you use the nd_pdo_mysql extension, as seen in below screenshot.

Since libmysql returns numeric types as strings, I use mysqlnd with nd_pdo_mysql in order to get native/strict data, so that numeric types are NOT returned as Strings.

From the MySQL official website: https://dev.mysql.com/downloads/connector/php-mysqlnd/

The MySQL native driver for PHP mysqlnd is a drop-in replacement for the MySQL Client Library libmysql for the PHP script language.
