pg_get_result - Get asynchronous query result

SYNOPSIS
       resource pg_get_result ([resource  $connection])

DESCRIPTION
       pg_get_result(3)  gets the result resource from an asynchronous query executed by pg_send_query(3), pg_send_query_params(3) or pg_send_exe-
       cute(3).

       pg_send_query(3) and the other asynchronous query functions can send multiple queries to a PostgreSQL server and pg_get_result(3)  is  used
       to get each query's results, one by one.

PARAMETERS
	      o $connection
		- PostgreSQL database connection resource.

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

EXAMPLES
       Example #1

	      pg_get_result(3) 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
";
		$rows1 = pg_num_rows($res1);
		echo "$res1 has $rows1 records

";

		$res2 = pg_get_result($dbconn);
		echo "Second call to pg_get_result(): $res2
";
		$rows2 = pg_num_rows($res2);
		echo "$res2 has $rows2 records
";
	      ?>

	      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
