help with php code

[Hippy]

I have a older mod on my current vb4.1.0
everything was fine.. till php was updated to 5.3.3
ez fix will be to down grade php to 5.2.*
anyway I am getting this error now
Deprecated: Assigning the return value of new by reference is deprecated in /path/file.php on line 111

and this

Warning: Cannot modify header information - headers already sent by (output started at [path]/file.php:111)

this error is from the apache error log
Warning: Directive 'register_long_arrays' is deprecated in PHP 5.3 and greater in Unknown on line 0

this is the code that the errors are referring to on that line in that file

PHP Code:

$bbcode_parser =& new vB_BbCodeParser($vbulletin, fetch_tag_list()); 


what does this call?

what would bring this up to todays standard?

I will be great full to you forever
thanks

solved, changed this

PHP Code:

$bbcode_parser =& new vB_BbCodeParser($vbulletin, fetch_tag_list()); 


to this

PHP Code:

$bbcode_parser = new vB_BbCodeParser($vbulletin, fetch_tag_list()); 


if someone could take the time to explain a little of this to me
it would be greatly appreciated
