[twitter-dev] php regex for twitter password

[Xpineapple]

I could probably play with regex all day and get no where (and so far
am).  While I could make some progress, I don't know all the rules for
a good password.  My intent is to ensure server (and service) are
safe.  With that in mind, can anyone provide a "fair enough" regex
example of sanatizing a password for twitter service? Thanx.
