Did the php errors just start occurring on their own or did you change, install, upgrade, etc. anything on your website?  If these php errors just started occurring on their own and you did not change, install, upgrade, etc. anything on your website then these php errors most likely mean there is/was a temporary problem with your host server.  If the php errors are still occurring then contact your web host support folks.  If you did change, install, upgrade, etc. anything on your website then you want to look at whatever you changed, installed, upgraded, etc.

Thanks for the reply. Haven’t changed or installed anything. They suddenly have begun to appear. Will contact my host provider and see what they have to say.

Getting memory limit changes and core files replacement from my host. Hope that solves the problem.

When these types of php errors suddenly start happening then there is a 99% chance that the problem is your host server itself. ie your web host is experiencing temporary server problems or your host is in the process of upgrading or migrating accounts, servers, etc.
