pg_fetch_object

I'm using PHP 5.0.4, PostgreSQL 8.0.2.

Docs say (http://www.php.net/manual/en/function.pg-fetch-object.php):

object pg_fetch_object ( resource result [, int row [, string
class_name [, array params]]] )

pg_fetch_object() returns an object with properties that correspond
to the fetched row's field names. It can optionally instantiate an
object of a specific class, and pass parameters to that class's
constructor.

I'm passing a class name string as the third parameter, but I only
get back a stdClass object. I also added an array of params as the
4th parameter to pass to the constructor, but it does not appear to
be called.

Has anyone successfully used this to create a class other than stdClass?

Thanks,

Works here with PHP 5.0.4 and PostgreSQL 8.0.3:

class Foo {
function Foo($arg) {
print "DEBUG: Foo($arg)\n";
}
}

pg_connect("dbname=test user=test password=test");

$result = pg_query("SELECT 'foo' AS val");
$obj = pg_fetch_object($result, 0, 'Foo', array("test"));
var_dump($obj);

pg_close();

The above code produces the following output:

DEBUG: Foo(test)
object(Foo)#1 (1) {
["val"]=>
string(3) "foo"
}

Could you post a minimal example that doesn't work?

Thanks for the example, it helped me figure out my dumb mistake. I
copied code from another place using a PHP abstraction library. I was
calling 'db_fetch_object' not 'pg_fetch_object'.

Thanks much,
