pg_fetch_result() returns the value of a particular
row and field (column) in a PostgreSQL result resource.

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

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

A string representing the name of the field (column) to fetch, otherwise
and int representing the field number to fetch. Fields are

Boolean is returned as “t” or “f”. All
other types, including arrays are returned as strings formatted

FALSE is returned if row exceeds the number
of rows in the set, or on any other error.
