I notice something in CMD, first time query is executing same time like from php all the time, but on the rest of the time that i will execute the query is faster from cmd, php is keeping the same execution time.
i also change the connection string (i remove host and port) and nothing changed.

Most probably.  If your existing connection string specifies something like "host=localhost port=5432 ..." just remove the host and port parameters and php will by default try to connect with unix domain socket.

Can we modify php connection?

Is php connecting through tcp whilst pgadmin is using unix domain socket?  Probably the query time is the same, but returning the result over tcp will be slower.

Hello,

I'm using php5.4.12 with extension=php_pgsql.dll enabled but the query that i'm trying to execute is faster on PgAdmin app.

SELECT title, ts_rank_cd(vector, query) AS rank FROM links, to_tsquery('english', 'risk') query WHERE query @@ vector ORDER BY rank DESC;

I'm not sure, what can i do to increase the speed of execution from php:

$start_time = microtime(true);
$query = "SELECT title, url, ts_rank_cd(vector, query) AS rank FROM links, to_tsquery('english', 'risk') query WHERE query @@ vector ORDER BY rank DESC LIMIT 10;";
$result = pg_query($connection, $query);
$end_time = microtime(true);

persistant connections are enabled in php.ini but i calculate only execution time from start to end.

Thanks, Emrah.
