pg_last_notice

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

pg_last_notice — Returns the last notice message from PostgreSQL server

Опис

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 php.ini.

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