# pg_last_notice

(PHP 4 >= 4.0.6, PHP 5)

pg_last_notice — Returns the last notice message from PostgreSQL server

### Description

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.

### Parameters

`connection`

  PostgreSQL database connection resource.

### Return Values

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

### ChangeLog

Version | Description
--- | ---
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().

### Examples

Example#1 pg_last_error() 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"
