Why does Pdo convert all of our int type to string type?

Why does Pdo convert all of our int type to string type ??? What parameters do you want to set ?? What are the considerations for this design ??? There is nothing to do with the data type except false =. besides, false = should be written false =. in this way, the data type is really related, why does mysql data Pdo convert all our int type to string type ???


What parameters do you want to set ??

What are the considerations for this design ??? A little pitfall



------ Solution --------------------
Except false =, there is nothing related to the data type.
Besides, false = writing is false =, so that it is actually related to the type.

The query results returned from the mysql database are all text and processed as strings, because PHP does not know your table structure. Both mysqli and pdo are like this!
