Answer 1

What PHP version? I'm assuming 7.x here (possibly) due to the 'deprecated' messages and the last 'fatal' error.

It's a two part matter...

1. The deprecated:

   PHP has made a change to use __construct() (two leading underscores) as the constructor instead of having the same name as the class itself. See the PHP 4 style constructors section (first section on the page) for more information.

   For example: In the file to ADOConnection has a deprecated constructor... the constructor likely looks like this:

   ADOConnection( ... ); // constructors with or without parameters
   

   ...but all of those can be replaced with:

   __construct( ... );
   

   You can make that change locally to resolve the deprecated messages.

2. The fatal error:

   With PHP 7.x, the mysql_* based functions are removed. See this API info.
