# 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

`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);
    ?>
