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

<?php
  $dbconn = pg_connect("dbname=publisher") or die("Could not connect");

  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);
?>
