Hi all,

I'm relativly new to regular expressions but I managed to create a working expression to validate dates (without leap years, and assuming people enter a valid 30 or 31 digit for a month).

This is the expressen: /^d[1-31]{2}-d[1-12]{2}-d[1900-2009]{4}$/

But I would like to have a dynamic regular expression like:

$yearSpan = (date("Y") - 110)."-".date("Y");
/^d[1-31]{2}-d[1-12]{2}-d[$yearSpan]{4}$/

When I try to use this expression it keeps telling me the compilation failed because a range out of order in character class.

I'm using this expression to validate dates of birth, and it would be nice not to update it every time a year passes by.

Any suggestions?
