pg_last_notice — Returns the last notice message from PostgreSQL server
pg_last_notice ( resource $connection [, int $option = PGSQL_NOTICE_LAST ] ) : mixed
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.
connection
PostgreSQL database connection resource.
option
One of PGSQL_NOTICE_LAST (to return last notice), PGSQL_NOTICE_ALL (to return all notices), or PGSQL_NOTICE_CLEAR (to clear notices).
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, or false on error.
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"
