Thanks Daniel,
but unfortunately I do not know the names of the fields, so that I can't
access the fields like "$population = $shape->values["Population"];", but
rather I should retrieve the results by using the column-number [0, 1, 2,
....]. But this does not work. Any further suggestion?

When you read query results using $layer->getShape(), the shapeObj
contains an array member called 'values' that contains all the field
values for this shape. See the shapeObj docs at
