With trying to make the jump to PHP7 I noticed that W3 Total Cache has some warnings when running it through the WP-Engine PHP7 Compatibility Checker, which are the following:

171 | WARNING | INI directive 'safe_mode' is deprecated since PHP 5.3 and removed since PHP 5.4.
---------------------------------------------------------------------------------------------------------------This plugin pretty much has the most errors regarding the use of mysql_ which I assume has to do something to do with connecting to the database.
So my question is if I should be concerned about these when I switch over to PHP7 in terms of the actual plugin still functioning properly?
Thanks for further information in advance!
