[support] class and globals in functions (maybe PHP)

I've to access an external DB (MS SQL so it is too complicated to rewrite the DB layer... bla bla)

So I plugged in my class to be seen inside hooks...

//catalog_base.inc $param="salve";

class Catalog_DB { function __construct($DBParam) { //... } public function test() { print("<!-- ciao ciao -->"); } }

$DBGorilla=new Catalog_DB($param);

//catalog.module $path = drupal_get_path('module', 'catalog'); require_once($path . '/catalog_base.inc');

//... hooks etc...

//test1 $DBGorilla->test();

function catalog_asearch() { global $DBGorilla; //test2 $DBGorilla->test(); $query=$DBGorilla->test(); return ""; }

test1 succeed test2 fail with Call to a member function test() on a non-object in ...

using $GLOBALS makes no difference... but drupal code is plenty of

global $user;

in functions

what's wrong?

thx
