pg_last_notice

Returns the last notice message from PostgreSQL server

Description

arraystringbool pg_last_notice(PgSql\Connection $connection, int $mode = PGSQL_NOTICE_LAST)

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.

Parameters

connection

An PgSql\Connection instance.

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.

Changelog

Version Description
8.1.0 The connection parameter expects an PgSql\Connection instance now; previously, a resource was expected.
7.1.0 The mode parameter was added.

Examples

Example #1 pg_last_notice example

<?php
  $pgsql_conn = pg_connect("dbname=mark host=localhost");
  
  $res = pg_query("CREATE TABLE test (id SERIAL)");
  
  $notice = pg_last_notice($pgsql_conn);
  
  echo $notice;
?>

The above example will output:

CREATE TABLE will create implicit sequence "test_id_seq" for "serial" column "test.id"
