# pg_transaction_status

(PHP 5 >= 5.1.0RC1)

pg_transaction_status -- Returns the current in-transaction status of the server.

## Описание

int pg_transaction_status ( resource connection )

Returns the current in-transaction status of the server.

Предостережение
pg_transaction_status() 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.

## Список параметров

`connection`

  PostgreSQL database connection resource.

## Возвращаемые значения

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 completed.

## Примеры

Пример 1. pg_transaction_status() 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'; } ?>`
