string pg_last_notice ( resource $connection )

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.

Список параметров

connection: PostgreSQL database connection resource.

Возвращаемые значения

A string containing the last notice on the given connection , or FALSE on error.

Версия	Описание
4.3.0	This function is now fully implemented. Earlier versions ignores database connection parameter.
4.3.0	The pgsql.ignore_notice and pgsql.log_notice `php.ini` directives were added.
4.0.6	PHP 4.0.6 has problem with notice message handling. Use of the PostgreSQL module with PHP 4.0.6 is not recommended even if you are not using pg_last_notice().
