pg_client_encoding — Gets the client encoding
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.
Nota:
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().
connection
Uma instância de PgSql\Connection.
Quando o parâmetro connection
for null
, a conexão padrão será usada.
A conexão padrão é a última conexão feita por pg_connect()
ou pg_pconnect().
A partir do PHP 8.1.0, usar a conexão padrão tornou-se defasado.
The client encoding.
Versão | Descrição |
---|---|
8.1.0 |
O parâmetro connection agora espera uma instância de PgSql\Connection;
anteriormente, um resource era esperado.

Exemplo #1 pg_client_encoding() example
<?php
// Assume $conn is a connection to a ISO-8859-1 database
$encoding = pg_client_encoding($conn);
echo "Client encoding is: ", $encoding, "\n";
?>
O exemplo acima produzirá:
Client encoding is: ISO-8859-1
