Need help running a function in a package

Question

Hi,
I am trying to execute a function called "IsGuest" which is stored in a package called "PK_USER_ROLE". This procedure returns a boolean as a result. Here is the PHP code in the web page I am using:
     echo "<br/>Test to execute a stored procedure";
     $s = oci_parse($conn, "begin :ret := PK_USER_ROLE.IsGuest(:userid); end;") or die ('Can not parse query');
     $myid = "huppe";
     oci_bind_by_name($s, ':ret', $r, 40);
     oci_bind_by_name($s, ':userid', $myid);
     oci_execute($s);
     echo "<br/>result=".$r;
     echo "<br/>Completed<br/><br/>";
     oci_free_statement($s);
     oci_close($conn);
In Oracle, here is the package definition:
create or replace
PACKAGE PK_USER_ROLE IS
function IsGuest (i_unique_id in varchar2) return boolean;
END;
All I get back when I view the PHP file in the browser is:
Test to execute a stored procedure
result=
Completed
PHP 5.3.8
Oracle 11g
OCI8 extension
Any help would be appreciated

I find it helpful to turn on errors and warnings in php.ini during
development.
    display_errors  = On
    error_reporting = E_ALL | E_STRICTor use the ini_set() equivalents in your script. For production,
make sure errors are logged but not displayed to users.
Your script then gives:
    $ php54 t.php
    Test to execute a stored procedurePHP Warning:  oci_execute(): ORA-06550: line 1, column 15:
    PLS-00382: expression is of wrong type
    ORA-06550: line 1, column 7:
    PL/SQL: Statement ignored in /tmp/t.php on line 10
    Warning: oci_execute(): ORA-06550: line 1, column 15:
    PLS-00382: expression is of wrong type
    ORA-06550: line 1, column 7:
    PL/SQL: Statement ignored in /tmp/t.php on line 10See the comment below the table in
http://docs.oracle.com/cd/E11882_01/appdev.112/e10646/oci03typ.htm#CEGIEEJI
+"The following two types are internal to PL/SQL and cannot be returned as values by OCI:+
+Boolean, SQLT_BOL+
+Record, SQLT_REC"+
Since PHP OCI8 is written in OCI, this limitation is inherited.
Try something like:
  $s = oci_parse($conn, "begin if (IsGuest(:userid) = true) then :ret := 1; else :ret := 0; end if; end;") or die ('Can not parse query');
