I'm fairly new to php and am having a bit of trouble modifying a script.

The script downloads an RSS weather feed, parses it and displays it on my IP Phone. What I am trying to do is to grab a couple of different variables and then print them later on.
I am trying to grab the name of the city from the RSS feed, the name of the province from the filename of the RSS feed, and the language from the filename of the RSS feed.
The feed that it displays is variable, the $zip syntax specifies which rss feed to download. $zip is in the following formant: xx-xxx_x where: xx=the province, xxx=the city code, x=the language. So I want to grab the xx (province) from the filename, and capitalize it, ie: BC. I want to grab the city from the rss file ie: Vancouver and the language from the RSS filename, ie: f for french and e for english.
