I see in the footnote of a reply I had about MySQL Library being deprecated.
As of PHP 5.5, the MySQL library has been officially deprecated. It is recommended to move to either MySQLi or PDO libraries for your mysql connectivity. See here for help choosing which interface you prefer: http://php.net/manual/en/mysqlinfo.api.choosing.php
Before I make a start, I wanted to ensure I understand that it is just the PHP used to connect to MySQL that is changing and not that MySQL is also being deprecated.
