Solve the problem of upgrading to php 7.2 in laravel 5.4 application

Question

I updated my version of laravel php to php 7.2 this week, and since then I have run into big problems in my laravel application . before upgrading php to 7.2, every thing worked efficiently.

The main problem is the count () and array_merge () functions that cause this error:

for a function, the array_merge()code is as follows:

$array = array_merge(
                $model->toSearchableArray(), $model->scoutMetadata()
            );

            if (empty($array)) {
                return;
            }

ErrorException · array_merge (): Argument # 1 is not an array.

and I encountered an error count(), for example, in this code, when the model does not return records and returns null:

count(TutorialReview::where('TutorialID', 5)->where('UserID', 6)->get())

count(): , .

laravel 5.4

, laravel 5.5 ?
