Trying to get property of non-object when used on object

Question

I have some PHP that is returning an object to a variable:

                $db = new Db(); 
                $db->db_connect(); 
                $testSelectQuery = $db->db_select('SELECT * FROM test');
                //$dbValue = $testSelectQuery[0]->testcol;
                $test = $testSelectQuery[0];
                FB::log($test);

Here is the output of $test:

Object {idtest: "1", testcol: "from db"}

Now when I try to echo one of the columns:

echo $test->testcol

I get an error:

Notice: Trying to get property of non-object

It was just defined as an object in the output. What am I doing wrong and how do I fix it?

Edit: vardump($test) results in: array(2) { ["idtest"]=> string(1) "1" ["testcol"]=> string(7) "from db" }

Where exactly do you try to echo a property? I don't see the code. — u_mulder, Jan 25 '16 at 20:03
When I am getting such an error, most of the time the database result is just empty ;-) Did you check on that? — Thomas Landauer, Jan 25 '16 at 20:05
I added the vardump. FB is just a PHP debugger http://www.sitepoint.com/debugging-php-code-with-firephp/ — David Tunnell, Jan 25 '16 at 20:07

It looks like $test is an associative array

Access it like this:

echo $test['testcol'];
