pg_get_result — Get asynchronous query result
Description
pg_get_result() gets an PgSql\Result instance 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.
Return Values
An PgSql\Result instance, or false if no more results are available.

Examples
Example #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";
?>
The above example will output:
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
