pg_transaction_status

Returns the current in-transaction status of the server.

&reftitle.description; `int` `pg_transaction_status` `resource` `connection`

Returns the current in-transaction status of the server.

`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.

&reftitle.parameters;

`connection`

- PostgreSQL database connection resource.

&reftitle.returnvalues;

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.

      if ($stat === PGSQL_TRANSACTION_UNKNOWN) {
          echo 'Connection is bad';
      } else if ($stat === PGSQL_TRANSACTION_IDLE) {
          echo 'Connection is currently idle';
      } else {
