pg_set_error_verbosity
(PHP 5 >= 5.1.0)
pg_set_error_verbosity — Determines the verbosity of messages returned by pg_last_error() and pg_result_error().
说明
int pg_set_error_verbosity
([ resource $connection
], int $verbosity
)
Determines the verbosity of messages returned by pg_last_error() and pg_result_error().
pg_set_error_verbosity() sets the verbosity mode, returning the connection's previous
setting. In PGSQL_ERRORS_TERSE mode, returned messages include severity, primary text, and
position only; this will normally fit on a single line. The default mode (PGSQL_ERRORS_DEFAULT)
produces messages that include the above plus any detail, hint, or context
fields (these may span multiple lines). The PGSQL_ERRORS_VERBOSE mode includes all available
fields. Changing the verbosity does not affect the messages available from
already-existing result objects, only subsequently-created ones.
参数
connection
PostgreSQL database connection resource. When
connection is not present, the default connection
is used. The default connection is the last connection made by
pg_connect() or pg_pconnect().
verbosity
The required verbosity: PGSQL_ERRORS_TERSE,
PGSQL_ERRORS_DEFAULT
or PGSQL_ERRORS_VERBOSE.
返回值
The previous verbosity level: PGSQL_ERRORS_TERSE,
PGSQL_ERRORS_DEFAULT
or PGSQL_ERRORS_VERBOSE.
范例
Example #1 pg_set_error_verbosity() example

if (!pg_connection_busy($dbconn)) {
pg_send_query($dbconn, "select * from doesnotexist;");
}
pg_set_error_verbosity($dbconn, PGSQL_ERRORS_VERBOSE);
$res1 = pg_get_result($dbconn);
echo pg_result_error($res1);
?>
