Constants for PDO_4D - Constants for PDO_4D
The constants below are defined by this driver, and will only be available when the extension has been either compiled into PHP or dynami-
cally loaded at runtime. In addition, these driver-specific constants should only be used if you are using this driver. Using driver-spe-
cific attributes with another driver may result in unexpected behaviour. PDO.getAttribute(3) may be used to obtain the PDO_ATTR_DRIVER_NAME
attribute to check the driver, if your code can run against multiple drivers.
o PDO::FOURD_ATTR_CHARSET ( integer) - Change the charset in which 4D returns data. (Default is UTF-8).
o PDO::FOURD_ATTR_PREFERRED_IMAGE_TYPES ( integer) - The requested format of the image, when selecting a row with a column type PIC-
TURE. It may be any type that 4D supports.
