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
( 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.
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 bool with PGSQL_NOTICE_CLEAR
,
or FALSE
on error.
