I've tried the CVS snapshot (located at
http://snaps.php.net/php5-latest.tar.gz [php5-200505060830]) and the
result is same.

{{{ Related PHP script:
<?php
$dbconn = pg_connect("dbname=test");

pg_query("LISTEN test");
sleep(5); // I'll type "NOTIFY test;" for three times
// from psql in here.
var_dump(pg_get_notify($dbconn));
var_dump(pg_get_notify($dbconn, PGSQL_NUM));
var_dump(pg_get_notify($dbconn, PGSQL_ASSOC));
?>
}}}

Expected and actual results are same as in the bug report.

Description:
------------
Second parameter (result_type) used in pg_get_notify() is ignored. When
we look at ext/pgsql/pgsql.c (in revision 1.324, Wed Apr 13 18:11:35
2005 from CVS):

Line 49: #define PGSQL_ASSOC 1<<0
Line 50: #define PGSQL_NUM 1<<1
Line 51: #define PGSQL_BOTH (PGSQL_ASSOC|PGSQL_NUM)
...
Line 4144: if (result_type & (PGSQL_NUM|PGSQL_BOTH)) {
...
Line 4178: if (result_type & (PGSQL_ASSOC|PGSQL_BOTH)) {

Both of the if conditions in the lines 4144 and 4178 returns true
(positive values) on any input. Thus, result_type param. always acts as
PGSQL_BOTH.

Line 4144 and 4178 may be replaced by below ones:

Line 4144: if (result_type & PGSQL_NUM) {
...
Line 4178: if (result_type & PGSQL_ASSOC) {

They're working well on my current system.

Reproduce code:
---------------
/*
* Any of these calls act as
* var_dump(pg_get_notify($dbconn, PGSQL_BOTH));
*/
var_dump(pg_get_notify($dbconn));
var_dump(pg_get_notify($dbconn, PGSQL_NUM));
var_dump(pg_get_notify($dbconn, PGSQL_ASSOC));

Expected result:
----------------
array(4) {
["message"]=>
string(1) "test"
["pid"]=>
int(2317)
}
array(4) {
[0]=>
string(1) "test"
[1]=>
int(2317)
}
array(4) {
["message"]=>
string(1) "test"
["pid"]=>
int(2317)
}

Actual result:
--------------
array(4) {
[0]=>
string(1) "test"
[1]=>
int(2317)
["message"]=>
string(1) "test"
["pid"]=>
int(2317)
}
array(4) {
[0]=>
string(1) "test"
[1]=>
int(2317)
["message"]=>
string(1) "test"
["pid"]=>
int(2317)
}
array(4) {
[0]=>
string(1) "test"
[1]=>
int(2317)
["message"]=>
string(1) "test"
["pid"]=>
int(2317)
}
