I have two possible values I need to match as the same.

Name/11 (This one is pulled from the source DB)
Name/11* (This is what I need to match to with or without the (*))

The pattern base name is pulled from a DB so I need to find a way to do 
this pragmatically.

Now some of the names have a forward slash / so I am using hash mark # 
as a delimiter.

I was able to find the "Name/11" using

#^Name/11#

or more specifically;

$value = "Name/11";
$pattern = "#^" . $value . "#";

But as for the (*), no glory.
I originally tried

#^Name/11?*#
#^Name/11\*#
#^Name/11.*#

It must be obvious I am having issues finding a way to escape the (*) 
and am not very versed with regex.

Can someone please explain the best way to escape an optional (*) from a 
string.  Or even point me to a good source.

I used http://www.regular-expressions.info/tutorial.html but was unable 
to find how to handle the star.

And if you bing up the *, it sort of gets ignored.

Thanks
