Matt :
Google recently changed their weather icons. If you use this script and notice that the icons aren’t showing up all you need to do is change line 115 to this:
$return_array['current_conditions']['icon'] = $xml->weather->current_conditions->icon['data'];
I guess it no longer requires that appended URL, I don’t use forecast on my website but you’ll probably have to change the icon line for that as well.
$return_array['forecast'][$i]['icon'] = $data->icon['data'];
Also thanks for the script Ashwin!
Hi there. I’m trying to find a code for a Portuguese city called “Ponta Delgada”. Since the script gets information by zip code and European zip codes are different, do you know how can i find a zip for a european country that works with google wheater api ?
I’ve tryed using the yahoo zip code of my city but didn’t worked
Hey, it supports a lot more functionality than I’ve included in this class. I will update it to accept the other features as soon as I get some free time. In the mean time, take a look at this blog
Curl is a plugin you have to enable btw…but file_get_contents is good as well. If you use file_get_contents, you might want to set the user agent ini_set(“user_agent”, “Your browsername here”); just incase.
With your code I had two problems: the cache enabled but no file, it does not return anything. So I have changed your example and the cache is handled by make_request(). The grabbing is made by file_get_contents() as I couldn’t find the curl thing. The other problem is your example doesn’t handle languages, so I’ve included in the get_weather_data() function as an optional parameter.

Using some of Tristan’s work, i modified the class so, from the original, it solves:
changed the old numeric-only zipcode var to a string var ($this->search), thus allowing the usage of google weahter’s supported search strings.
cache_time was not being considered in the code, now it is
added language support as a class property ($this->language)
cache file autogeneration using base64_encode to avoid encoding problems with filesystems
new class property ($this->cache_file_encoding) to set cache file encoding (defaults to ISO-8859-1)
moved the gweather icons url string to a class property ($this->gweather_icons_url) for faster modification and easier usage
filtered all vars used as url parameters using urlencode() function to avoid errors
There it goes:

New revision added. Google’s ICON url changed and the code has been updated.
Thank you so much for sharing this script. Its awesome.
Code updated again at line 123.
Changed from
$return_array['forecast'][$i]['icon'] = ‘http://img0.gmodules.com/ig/‘ . $data->icon['data'];
to
$return_array['forecast'][$i]['icon'] = ‘http://img0.gmodules.com/‘ . $data->icon['data'];

Thanks Matt, I just realized this change today as well. I will update the code.
what about this
…
if ($diff <= 3600){ ….
should be
…
if ($diff cache_time){ ….
if ($diff cache_time){
if ($diff <= $this->cache_time){
(dammend textprocessor)
@Tomako
Good catch! Code updated, thanks.
@admin
Would it be poss to help change it so i could use city name instead as im in the uk and we dont use zip code?
I’m looking to include a similar class in a personal project I’m working on (GNU License). What’s your license on this PHP Class?
Hey, it would be GNU as well. I will update the post…thanks.
Great! I’ll drop you a line if/when my project gets completed.
Thanks for your work on this. It’ll save me a good chunk of time.
