使用preg_replace附加值

Question

Assume i have the following hrefs:

.... href="http://localhost/centboox/usedtextbooks/desc/30" ....

I would like to through all of them and add ** just before closing the href's double quotation:

... href="http://localhost/webname/pagename/desc/30*******" ...

Asterisks represent some input e.g. ?q=all&a=search_text

How can i do this via preg_replace in PHP.

Thanks
