pg_set_error_verbosity()

(PHP 5 >= 5.1.0, PHP 7)

Determines the verbosity of messages returned by pg_last_error() and pg_result_error()

说明

pg_set_error_verbosity([resource $connection],int $verbosity): int

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$connectionis 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.
