PG_TRANSACTION_STATUS(3)PG_TRANSACTION_STATUS(3)pg_transaction_status - Returns the current in-transaction status of the server.SYNOPSIS
int pg_transaction_status (resource $connection)
DESCRIPTION
Returns the current in-transaction status of the server.
Caution
pg_transaction_status(3) will give incorrect results when using a PostgreSQL 7.3 server that has the parameter autocommit set to
off. The server-side autocommit feature has been deprecated and does not exist in later server versions.
PARAMETERS
o $connection
- PostgreSQL database connection resource.
RETURN VALUES
The status can be PGSQL_TRANSACTION_IDLE (currently idle), PGSQL_TRANSACTION_ACTIVE (a command is in progress), PGSQL_TRANSACTION_INTRANS
(idle, in a valid transaction block), or PGSQL_TRANSACTION_INERROR (idle, in a failed transaction block). PGSQL_TRANSACTION_UNKNOWN is
reported if the connection is bad. PGSQL_TRANSACTION_ACTIVE is reported only when a query has been sent to the server and not yet com-
pleted.
EXAMPLES
Example #1
pg_transaction_status(3) example
<?php
$dbconn = pg_connect("dbname=publisher") or die("Could not connect");
$stat = pg_transaction_status($dbconn);
if ($stat === PGSQL_TRANSACTION_UNKNOWN) {
echo 'Connection is bad';
} else if ($stat === PGSQL_TRANSACTION_IDLE) {
echo 'Connection is currently idle';
} else {
echo 'Connection is in a transaction state';
}
?>

PG_GET_RESULT(3)PG_GET_RESULT(3)pg_get_result - Get asynchronous query resultSYNOPSIS
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
