(PHP 5 >= 5.1.0)
pg_transaction_status — Returns the current in-transaction status of the server.
$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.
connection
PostgreSQL database connection resource.
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.
Example #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';
}
?>

This function is implemented in C, so there's no way to mimic it in SQL for older versions of PHP. But you can mimic some of the functionality by using a wrapper which keeps track of when you begin and commit/rollback transactions.
