pg_fetch_result — Returns values from a result resource
Description
pg_fetch_result() returns the value of a particular row and field (column) in a PostgreSQL result resource.
Note:
This function used to be called pg_result().
Parameters
-
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.

other types, including arrays are returned as strings formatted
in the same default PostgreSQL manner that you would see in the
psql program. Database NULL
values are returned as NULL.
FALSE is returned if row exceeds the number
of rows in the set, or on any other error.
Examples

<?php
$db = pg_connect("dbname=users user=me") || die();
$res = pg_query($db, "SELECT 1 UNION ALL SELECT 2");
$val = pg_fetch_result($res, 1, 0);
echo "First field in the second row is: ", $val, "\n";
