need help modifying script

Posted on 16th Feb 2014 07:03 pm by admin

Hi guys,

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

This is the script:
Code: <?php

An example of what the RSS feed looks like:
http://www.weatheroffice.gc.ca/rss/city/bc-85_e.xml

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.

I then want to be able to print these variables later in the script, ie: $city = Victoria, BC
I also want to be able to display a different text depending on the language, ie: if f(french) then print: Conditions météo actuelles if e(english) print: Current weather conditions and be able to print that with: $titlelang

I know im asking a lot, but if anyone can point me in the right direction it would be greatly appreciated.
