I am not an expert on PHP but I have been programming in Perl for four
years so I can tell you what I would use in Perl and you can see if that
works in PHP. (I am almost sure they would be the same...)

/\$\d\d\.\d\d\.d/

It looks to me like you are forgetting to escape your period making the
interpreter think it is "any character" rather than a literal period. I am
not sure what the {2} is because I have never used that. Does that part of
it really work that way?

Good luck, hope that helps.
