One fun solution would be writing a module which screen scapes http://www.direct.gov.uk/en/Governmentcitizensandrights/LivingintheUK/DG_073...
That URL doesn't have the feel of one that will still work in a year or two's time!
Otherwise, searching for "national holiday web service" will probably be the most likely way to find a solution. I had a quick look and found one or two things. (One of them it seemed you had to pay for.) If you have HTTP client libraries (which PHP may have) and XML parsing libraries something like this would probably by quite easy to use.
Thanks for this pointer; I haven't found anything directly useful yet but it looks like a possible way forward.
