Hello Daniel,
Thanks for your response.
Ahhh -- so after a successful query, the PHP program must keep executing
pg_get_result($cnx) until a NULL result is obtained !!
And ONLY THEN does transaction status transition from
PGSQL_TRANSACTION_ACTIVE to PGSQL_TRANSACTION_INTRANS.
OK -- makes sense to me -- I will change the code accordingly.

BTW -- this PostgreSQL newbie (bye bye mysql) is getting a nice warm fuzzy
feeling, about PostgreSQL and its amazingly helpful community :)
Best,
Steve

Subject: Re: [GENERAL] *** QUESTION *** After successful 'BEGIN;' command --
why PGSQL_TRANSACTION_ACTIVE and not PGSQL_TRANSACTION_INTRANS?

And yes, I am using pg_send_query(...) to execute the BEGIN; command, so

to get a result resource returned. (Please see my forthcoming emailed
response to Adrian Klaver, wherein I provide the PHP source code that

requests.)
After successfully calling pg_send_query($cnx, $query),
pg_transaction_status($cnx) will return PGSQL_TRANSACTION_ACTIVE
until the results have been collected by looping over pg_get_result($cnx).
This is for any query, not specifically $query="BEGIN".
Example:
<?php
if (pg_send_query($dbcnx, "BEGIN")) {
do {
$res=pg_get_result($dbcnx);
// error processing here
} while ($res);
echo pg_transaction_status($dbcnx);
?>
This will output 2, which corresponds to PGSQL_TRANSACTION_INTRANS
as expected.
OTOH if commenting the call to pg_get_result($dbcnx), then
it ouputs 1 (PGSQL_TRANSACTION_ACTIVE) as you mentioned.
Best regards,
