note 59202 added to function.pg-send-query

Note that if you send a query without calling pg_get_result() for the previous one (supposing it has finished and the connection is not busy), the previous query will get discarded. See for yourself (tested on php4.4.0, postgres8.0.4, Linux/FreeBSD) : <? $conn = pg_connect("dbname=template1 host=localhost user=pgsql"); if ($conn === FALSE) exit("Can't connect to db"); $q = array(); // send some queries foreach (range(0, 500) as $i) stack_query($q, $conn, "SELECT 'query $i' AS str;"); // receive them while (true) { $left = stack_query($q, $conn); echo "$left left... "; $result = pg_get_result($conn); if ($left == 0 && $result === FALSE) break; $row = pg_fetch_assoc($result); // depending on race conditions, you wont get all your original queries here. echo "got $row[str]\n"; } function stack_query(&$queries, $conn, $sql = FALSE) { if ($sql !== FALSE) $queries[] = $sql; while (count($queries) && !pg_connection_busy($conn)) pg_send_query($conn, array_shift($queries)); return count($queries) + (pg_connection_busy($conn) ? 1 : 0); } ?> You will have to write a higher level of abstraction if you want a "send all queries now, receive them later" behaviour. ---- Manual Page -- http://www.php.net/manual/en/function.pg-send-query.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+59202 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+59202&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+59202&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+59202&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+59202&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+59202&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+59202&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+59202&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+59202&report=yes Search -- http://master.php.net/manage/user-notes.php
