I’m trying to find the APIs on Zephyr, https://docs.zephyrproject.org/latest/reference/bluetooth/index.html , using these APIs can get
• ConnInterval,
• whether Data Length Extension is enable or not, and
• which PHY is using, 1M uncoded, 2M uncoded or 1M coded?
But I haven’t found them, so send this email for help.

The API to get information on a connection is bt_conn_get_info(). Out of the parameters you mentioned you can get at least get the interval, however DLE or PHY information is not currently exposed (contributions are welcome!).
