# pg_get_result

(PHP 4 >= 4.2.0, PHP 5)

pg_get_result -- Get asynchronous query result

## Leírás

resource pg_get_result ( [resource connection] )

pg_get_result() gets the result resource from an asynchronous query executed by pg_send_query(), pg_send_query_params() or pg_send_execute().

pg_send_query() and the other asynchronous query functions can send multiple queries to a PostgreSQL server and pg_get_result() is used to get each query's results, one by one.

## Paraméterek

connection

  PostgreSQL database connection resource.

## Visszatérési értékek

The result resource, or `FALSE` if no more results are available.

## Példák

Példa 1. pg_get_result() example

`<?php
$dbconn = pg_connect("dbname=publisher") or die("Could not connect");
if (!pg_connection_busy($dbconn)) {
pg_send_query($dbconn, "select * from authors; select count(*) from authors;");
}
$res1 = pg_get_result($dbconn);
echo "First call to pg_get_result(): $res1\n";
$rows1 = pg_num_rows($res1);
echo "$res1 has $rows1 records\n\n";
$res2 = pg_get_result($dbconn);
echo "Second call to pg_get_result(): $res2\n";
$rows2 = pg_num_rows($res2);
echo "$res2 has $rows2 records\n";
?>`

A fenti példa a következő kimenetet adja:

    First call to pg_get_result(): Resource id #3
    Resource id #3 has 3 records

    Second call to pg_get_result(): Resource id #4
    Resource id #4 has 1 records
