pg_get_result
PG_GET_RESULT(3) PG_GET_RESULT(3)
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
