Use Variables (eg: $bbuserinfo[username]) in posts?

[Skyrider]

I know this isn't possible without some kind of alteration to the php files or plugin, but I was hoping someone could help me out.

In this thread: https://vborg.vbsupport.ru/showthread.php?t=81759

There's a code how to do use the username variable within signatures:

Edit includes/functions_showthread.php, find:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
$post['signature'] = parse_bbcode($post['signature'], 'nonforum', $vboptions['allowsmilies']);
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

AFTER THAT add:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
				// Logician Hack : Admin signatures parsed for vb variables
				if ($post['usergroupid']==6) 
				{
					@eval('$post[signature] = "' . addslashes($post['signature']) . '";');
					$post['signature'] = stripslashes($post['signature']);
				}
				// Logician Hack : Admin signatures parsed for vb variables
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

That's all. ;)

Logician \\=^))

But I'd like it to be within posts. and I'm afraid that code is for the older vbulletin version as well.

I appreciate the help! If you wish to help out .
