The following code causes a 'deprecated' error in PHP 5.3... Is there a substitute for it?
$this->widgets[$widget_class] = & new $widget_class();

It'd be nice if you could specify what exactly the error message says, but I'm guessing it's informing you that object assignment by reference (=&) is deprecated. Objects are always assigned and passed by reference as of PHP 5, so including & is unnecessary. Simply drop the reference operator:
$this->widgets[$widget_class] = new $widget_class();

I don't think "assignment by reference" in general is deprecated but "new object" assignment is. See php.net/manual/en/migration53.deprecated.php - "Assigning the return value of new by reference is now deprecated."

@Phil Good link, I was looking for a reference (no pun intended) in the manual, but couldn't find one.

Same, had to use Google as I didn't think to look in the migrations section
