[PHP5 AdoDB] Correct return value after oracle package function call should be a string and I get a

Hello.

I'm using PHP5 and ADODb(could not find a version number for the life of me,
the closest thing I could
find is an "old-changelog.htm" file topping version 3.92.22 well buried in a
docs folder).
I have this php code:

/*getTitoloFromID si riferisce alla tabella CONF_RELAZIONI!!!*/
function getTitoloFromID( $anno, $trimestre,$id )
{
$r_titolo = str_pad('', 50,'@');

$params = array(
'p_anno' => $anno,
'p_trimestre' => $trimestre,
'p_id' => $id,
'r_titolo' => &$r_titolo
);

trace( 'Parametri: ');
trace( $params );

$sql = "BEGIN :r_titolo :=
PKG_RELAZIONI.getTitoloFromID(:p_anno,:p_trimestre,:p_id); END;";
$this->Execute($sql, $params);
trace( 'Titolo nella chiamata: '.$r_titolo);
return $r_titolo;
}

Backend is Oracle(don't know the version, again don't have a clue where to
look for it, but I'm
pretty sure it's above 9 because we use constructs that... d'oh! are present
from ver 9 on :D).

When I check the LOGS table in my db, I see the *correct* result being
added.
When this value gets to PHP, however, something happens and I receive the
value "1"(without quotes)
without any apparent reason. The correct value is a string and, again, it
gets displayed in the logs
table correctly, hence I assume the SQL is correct.
I am also sure it does not depend on the params(trimestre means quarter, the
first thing I thought was
that I could be misplacing parameters or something like that) but that's not
the case either.
Return value is properly sized because I had already received the "invalid
buffer size" error.
Other calls use the same "pattern" and they all work beautifully.
I am pretty much at loss and would love some help nailing this because I
can't seem to
wrap my head around it :-)

Many thanks for reading this :-)

Andrew
