Because the bottom is turned into a string when the array is returned.

OK Pdo::attr_emulate_prepares set to false, it will not automatically turn.
There is the use of code to turn, TP and YII2 I have seen, the implementation of the same way.

This is the TP example to solve PHP from the database out of the field is all string type
