pg_last_notice
(PHP 4 >= 4.0.6, PHP 5, PHP 7)
pg_last_notice — Returns the last notice message from PostgreSQL server
Description
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.
-
option -
One of
PGSQL_NOTICE_LAST(to return last notice),PGSQL_NOTICE_ALL(to return all notices), orPGSQL_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 boolean with PGSQL_NOTICE_CLEAR,
or FALSE on error.
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"
