WordPress and PHP 7 issues on Windows

Hi,

due to paypal security changes it seems that I would need to run wordpress with php 7 since php 7 comes with one of the latest versions of openssl bundled in.

After upgrading php from 5.4 to 7.0.4, wordpress would not run anymore with the following error:
[28-Mar-2016 12:40:36 UTC] PHP Fatal error: Uncaught Error: Call to undefined function mysql_error() in C:\inetpub\wwwroot\wp-content\plugins\revslider\inc_php\framework\db.class.php:29

Apparently with PHP7 you need to use PDO or mysqli and neither of these are supported by WordPress ??

Can you please confirm that wordpress runs or not runs with php 7 on Windows ?

I am running on Windows Server on IIS.

I noticed on 5.4 I have the following extensions available:

extension=php_mysql.dll
extension=php_mysqli.dll

On 7.0.4 I only see:

extension=php_pdo_mysql.dll
extension=php_mysqli.dll

Any advise would be appreciated.
thanks,
