Explain this line of code.

can someone explain this

$vbulletin->GPC['message'] =& str_replace($str1, $str2, $vbulletin->GPC['message']);

PHP:

first I want to know what the "->" does in

$vbulletin->GPC['message']

next I want to know what the =& does.

Thanks

 

-> - It's called arrow operator, if I'm not mistaken. It's used to access methods and variables in objects.
