Return the TTY name associated with the connection

Description

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

pg_tty() returns the TTY name that server side debugging output is sent to on the given PostgreSQL connection instance.

Note:
pg_tty() is obsolete, since the server no longer pays attention to the TTY setting, but the function remains for backwards compatibility.

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

A string containing the debug TTY of the connection.

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.
