During the update from OMV3 to OMV4 also php should have been updated to php7.
Did you get any error messages during the update?

Not sure if it is safe to just purge php5. Do you have backup of the original OMV3 installation?
Hope somebody else can help.
I backuped the whole system (got an update from before the update too) and did apt-get purge 'php5*' .
Seems to be fixed. No errors and the system is still working so far.
