Connecting
To connect to CockroachDB, 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 CockroachDB Sys", "", "");
Provide a Driver Connection String
To connect using an ODBC connection string:
$cnx = odbc_connect("DRIVER={CData ODBC Driver for CockroachDB};User=root;Password=root;Database=system;Server=localhost;Port=26257", "", "");
