That's incorrectly syntactically. Won't run.
Ok, let's write some code to show how this can be done:
class SearchHelper extends AjaxACApplication {
private $dbh;
public function __construct() {
$this->dbh = $GLOBALS['dbh'];
}
}
Better yet, pass the database host in the cons

Merlin,
if you are using php5 the var keyword is no longer valid; that was used in
classes in php4.
if you want to structure your classes properly you need to study PPP

Refer to the global on the constructor.
Anyway, using a global like that is not a good practice. Just pass the
variable to the constructor.

class, but somehow that does not work. global also does not have any effect.
In the following example I would like to be able to access $dbh from
inside the class like I did in that example. This does not work. C
