PHP considers null is equal to zero

In PHP, ($myvariable==0) When $myvariable is zero, the value of the expression is true; when $myvariable is null, the value of this expression is also true. How can I exclude the second case? I mean I want the expression to be true only when $myvariable is zero. Of course I can write

($myvariable != null && $myvariable == 0)

But is there other elegant way to do this?

I hade faced a similar issue in one of my projects, with a minor difference that I was also using the values ZERO as a valid value for my condition. here's how I solved it using simple logic to separate NULL from zero and other values.

    if (gettype($company_id) === 'NULL') {
        $company = Company::where('id', Auth::user()->company_id)->first();
    } else {
        $company = Company::where('id', $company_id)->first();
    }
