(PHP 4 >= 4.0.6, PHP 5, PHP 7, PHP 8)

Returns the last notice message from PostgreSQL server

Description

pg_last_notice(PgSql\Connection $connection, int $mode = PGSQL_NOTICE_LAST): array|string|bool

pg_last_notice() returns the last notice message from the PostgreSQL server on the specified connection. The PostgreSQL server sends notice messages in several cases, for instance when creating a SERIAL column in a table.

With pg_last_notice(), you can avoid issuing useless queries by checking whether or not the notice is related to your transaction.

Notice message tracking can be set to optional by setting 1 for pgsql.ignore_notice in Ini.

Notice message logging can be set to optional by setting 0 for pgsql.log_notice in Ini. Unless pgsql.ignore_notice is set to 0, notice message cannot be logged.

Parameters

connection: Connection
mode: One of PGSQL_NOTICE_LAST (to return last notice), PGSQL_NOTICE_ALL (to return all notices), or PGSQL_NOTICE_CLEAR (to clear notices).

Return Values

A string containing the last notice on the given connection with PGSQL_NOTICE_LAST, an array with PGSQL_NOTICE_ALL, a bool with PGSQL_NOTICE_CLEAR.
