pg_get_result — 取得异步查询结果
pg_get_result() 从由 pg_send_query()、pg_send_query_params() 或 pg_send_execute() 执行的异步查询中获取 PgSql\Result 实例。
pg_send_query() 和其它异步查询函数可以向 PostgreSQL 服务器发送多个查询，而 pg_get_result() 则用来逐个获取查询结果。
PgSql\Result 实例，或者没有更多查询结果，则返回 false。
| 版本 | 说明 |
|---|---|
| 8.1.0 | 现在返回 PgSql\Result 实例，之前返回 resource |
| 8.1.0 |
现在 connection 参数接受 PgSql\Connection
实例，之前接受 resource。

示例 #1 pg_get_result() 示例
<?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";
?>以上示例会输出：
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
