pg_client_encoding

(PHP 4 >= 4.0.3, PHP 5, PHP 7, PHP 8)

pg_client_encoding — Gets the client encoding

Description

pg_client_encoding(?PgSql\Connection $connection = null): string

PostgreSQL supports automatic character set conversion between server and client for certain character sets. pg_client_encoding() returns the client encoding as a string. The returned string will be one of the standard PostgreSQL encoding identifiers.

Note:

This function requires PostgreSQL 7.0 or higher. If libpq is compiled without multibyte encoding support, pg_client_encoding() always returns SQL_ASCII. Supported encoding depends on PostgreSQL version. Refer to the PostgreSQL Documentation supported encodings.

The function used to be called pg_clientencoding().

Parameters

connection

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

Warning

As of PHP 8.1.0, using the default connection is deprecated.

Return Values

The client encoding.

Changelog

Version Description
8.1.0 The connection parameter expects an PgSql\Connection instance now; previously, a resource was expected.
8.0.0 connection is now nullable.
