Code Examples

pg_set_client_encoding( [PgSql\Connection$connection], string$encoding ): int

pg_set_client_encoding sets the client encoding and returns 0 if success or -1 if error.

PostgreSQL will automatically convert data in the backend database encoding into the frontend encoding.


The function used to be called pg_setclientencoding.



An PgSql\Connection instance. When connection is unspecified, the default connection is used. The default connection is the last connection made by pg_connect or pg_pconnect.

The exact list of available encodings depends on your PostgreSQL version, so check your PostgreSQL manual for a more specific list.
