pg_get_result --  Get asynchronous query result


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.



PostgreSQL database connection resource.

Return Values

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


Example 1. pg_get_result() example

= 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);
"First call to pg_get_result(): $res1\n";
$rows1 = pg_num_rows($res1);
"$res1 has $rows1 records\n\n";
$res2 = pg_get_result($dbconn);
"Second call to pg_get_result(): $res2\n";
$rows2 = pg_num_rows($res2);
"$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
