pg_set_error_verbosity
(PHP 5 >= 5.1.0, PHP 7)
pg_set_error_verbosity — 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

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:
