Обсуждение: How to print explain using PHP
I'm working with PHP and Postgres, and if I try to do an EXPLAIN query, with PHP, to the postgres backend the output goes to the error_log file of apache and I don't know how to redirect that output to the browser. Does anyone know how I can do this?

Good point, before some time somebody (Bruce?) ask if anything is
needful add to PostgreSQL extension in PHP. You found that...
PHP not support libpq's routine:
PQnoticeProcessor
PQsetNoticeProcessor( PGconn *conn,
PQnoticeProcessor proc,
void *arg);

Any way, I'm doing some messy things to get what I want, but it is a very needfull extension.

I think the issue here was that these functions don't make any sense for PHP because you can't register C functions. > > On Tue, 9 Jan 2001, Martin A.

I mean (I know) that you can register some common (internal) PHP
function and this function can call your PHP function. It is some used in
XML Expat parser that use element handlers (functions).
It's very good resolvable in PHP... see php-4.0b3/ext/xml/xml.c as example

Should we add this to our TODO list? -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 853-3000 + If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania 19026

Quick look to PHP:-)
libphp/zend_execute_API.c: call_user_function()

What about changing the PHP function php_pgsql_do_connect so that it calls PQsetNoticeProcessor to preserve the last NOTIFY string somewhere. And we would invent new PHP function pg_notifymessage (or whatever) to extract the string later on. > OK, this is why I never added it to the TODO list. Should we add this > to our TODO list? I don't think so, if the TODO should only include things to do with the PostgreSQL source code. -- Tatsuo Ishii
