PHP :: MySQLI Values Returning Bits And Ints As String

I have a project made in flex, using php data services to access a sql server database, and I need to convert it to mysql, I have changed all my php services from sqlsrv to mysqli. Something like this:

$this->connection = mysqli_connect(SERVER,USERNAME,PASSWORD,DATABASE); // Start Connection
$ssqlstring = "select * from Users";
$runssql = mysqli_query($this->connection, $ssqlstring);
while($user = mysqli_fetch_array($runssql)) {
$users[$user["ID"]] = $user;
} return $users;

It worked fine on sqlsrv but with mysqli it returns to flex the INT, BIT or DATE values as string the main Datatypes on mysql are INT,VARCHAR,BIT(1),DATETIME,DATE (same as sqlsrv)
and on the flex the return types are mainly as object[]
