To connect to Snowflake, you can use either a DSN or an ODBC connection string. Both of these methods use the odbc_connect function.

Connect to a DSN

To connect using a DSN:

$cnx = odbc_connect("CData Snowflake Sys", "", "");

Provide a Driver Connection String

To connect using an ODBC connection string:

$cnx = odbc_connect("DRIVER={CData ODBC Driver for Snowflake};url=https://myaccount.region.snowflakecomputing.com;user=Admin;password=test123;Database=Northwind;Warehouse=TestWarehouse;Account=Tester1;", "", "");
