pg_trace
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.
pg_transaction_status
(PHP 5 >= 5.1.0)
pg_transaction_status — Returns the current in-transaction status of the server.
Description
int pg_transaction_status
( resource
$connection
)Returns the current in-transaction status of the server.
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.
Parameters
-
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 completed.
Examples
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';
}
?>
