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
