Adjusting a custom WordPress plugin to work with PHP7.1

Hello,

I have updated one very old WordPress website to the newest WP version & PHP 7.1 and one custom plugin developed ages ago stopped working. It's a simple plugin for making bookings on the site. It should be long work.

I need to tweak this plugin to work with PHP 7.1. I'm getting following error (doesn't have to be the only one):

Deprecated: mysql_query(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in /var/www/clients/client4/web18/web/wp-content/plugins/rezervace/[login to view URL] on line 4

Warning: mysql_query(): Access denied for user ''@'localhost' (using password: NO) in /var/www/clients/client4/web18/web/wp-content/plugins/rezervace/[login to view URL] on line 4

Warning: mysql_query(): A link to the server could not be established in /var/www/clients/client4/web18/web/wp-content/plugins/rezervace/[login to view URL] on line 4

Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in /var/www/clients/client4/web18/web/wp-content/plugins/rezervace/[login to view URL] on line 5

Can anyone help me with that please?

Thanks a lot, Jakub
