# pg_fetch_object

(PHP 3 >= 3.0.1, PHP 4, PHP 5)

pg_fetch_object -- Fetch a row as an object

## Описание

object pg_fetch_object ( resource result [, int row [, int result_type]] )
object pg_fetch_object ( resource result [, int row [, string class_name [, array params]]] )

pg_fetch_object() returns an object with properties that correspond to the fetched row's field names. It can optionally instantiate an object of a specific class, and pass parameters to that class's constructor.

> Замечание: Эта функция устанавливает NULL-поля в значение `NULL` PHP.

Speed-wise, the function is identical to pg_fetch_array(), and almost as fast as pg_fetch_row() (the difference is insignificant).

> Замечание: row became optional in PHP 4.1.0.

> Замечание: result_type default changed from `PGSQL_BOTH` to `PGSQL_ASSOC` from PHP 4.3.0, since the numeric index was illegal.

> Замечание: class_name and params were added in PHP 5.0. The old form with result_type still exists for backwards compatibility.

## Список параметров

result

  PostgreSQL query result resource, returned by pg_query(), pg_query_params() or pg_execute() (among others).

row

  Row number in result to fetch. Rows are numbered from 0 upwards. If omitted, next row is fetched.

result_type

  Ignored and deprecated. Defaults to `PGSQL_ASSOC`.

class_name

  The name of the class to instantiate, set the properties of and return. If not specified, an stdClass object is returned.

params

  An optional array of parameters to pass to the constructor for class_name objects.

## Возвращаемые значения

An object with one attribute for each field name in the result. Database NULL values are returned as `NULL`.

`FALSE` is returned if row exceeds the number of rows in the set, there are no more rows, or on any other error.
