pg_transaction_status
(PHP 5 >= 5.1.0)
pg_transaction_status — Returns the current in-transaction status of the server.
설명
int pg_transaction_status
( resource $connection
)
Caution
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.

반환값
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.
