I have recently upgraded my O/S to OpenSuse Leap 15.0 and that installed PHP7 and Zend 3.2.0. I use bacula for backups and have webacula as a browser front end. I had some problems even getting this to work but eventually found ways around the problems but then I was getting two messages which seem to indicate bugs in the Zend framework. I am going to post separate reports for each.
This is about Db/Table/Abstract.php which comes up with a message that count() is using the wrong type of component. At line 1307 there is the code:
'$keyValuesCount = count($keyValues);
which is causing the error. Immediately following this is a test to check whether $keyValues is an array and if not to convert to an array. By moving the line that causes the error to follow the test the error is avoided.
