I've just installed CiviCRM on a Joomla 3.5.1 site to learn how to use it. I am seeing an issue that I have a question about.
As long as I use Php 5.6 the installation works properly. If I try to use Php 7 everything on the Joomla site works except Civicrm. From the backend if I select Civicrm I get this error: Call to undefined function dl()
As soon as I go back to Php5.x all is well. The database is using utf8mb4_general_ci collation and mysqli.
Is there anything that needs to be done to use Php7 that I haven't found?
