pg_fetch_object — Fetch a row as an object

Description

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

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.

Note: This function sets NULL fields to the PHP NULL value.

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