Environment Canada forecast script (for www.weatheroffice.gc.ca)
This script is along the lines of the carterlake.org NOAA 5-day script especially for the Canadian stations using Environment Canada as the source of the data. It uses a new set of customized icons with PoP displayed like the www.crh.noaa.gov website used by Tom's script. Examples:
 |
PoP: 40% ==> |
 |
 |
PoP: 100% ==> |
 |
 |
PoP: 70% ==> |
 |
To use it, you need to download the ec-forecast-V6-02.zip file and unzip, then upload to your website. The scripts and GIF icons are included in the zip file. The script also requires the URL for the printable forecast for your area. Instructions are included with the source file and the ec-forecast-README.txt for the script.
As of V2.16, ec-forecast.php now supports the new transparent PNG icons created by Thayer Fox who has kindly permitted distribution from this site.
As of V3.00, the ZIP version contains these PNG icons.
 |
PoP: 40% ==> |
 |
 |
PoP: 100% ==> |
 |
 |
PoP: 70% ==> |
 |
Download and unpack the ec-icons-png.zip and configure the ec-forecast.php to use the .png images in the settings area.
The script supports both English and French languages via the lang=en or lang=fr parameter.

With Version 1.08, a new $currentConditions string is formatted with the current conditions of the selected city. If the city's conditions are based on a nearby airport, then a current conditions icon and short weather description are included. You can enable automatic printout by using $showConditions = true; in the ec-forecast.php script which will cause it to print before the alerts and forecast section. If you're 'quitely' including the script on your page, you can still print $currentConditions; where you'd like the conditions display to appear.
Version 2.00 brings a major rewrite of the script to accomodate a major change in the EC Forecast pages. Included with the .ZIP distribution are the new icons now in use by EC for the forecast site. The V2.00 script is compatible with the prior icon set distributed with the Version 1.nn script.
Version 2.16 included multi-forecast capability, improved diagnostics, support for the new transparent PNG icons, and additional settings for display of date with icon and/or detail forecast legend.
Version 3.00 is a major rewrite to support the EC website changes in October, 2014. The .zip distribution now includes the current .PNG format weather icons with POP stamps.
Version 3.02 has a major change in display of the temperature forecasts with the icons. It is now done by an extract of the value from the detail text forecast instead of the old method of using the values from the icon HTML. This should provide a more consistent presentation of Min/Max values for the icons.
Version 4.02 now uses cURL functions and uses HTTPS to access the EC website.
Version 5.00 is a major rewrite of the script to use the EC XML data instead of page scraping the EC website. V5.00 includes an Almanac and a 24-hour rolling forecast that can be displayed via new settings (default is to display both). The XML parsing should insulate us from further tweaks with the EC website page design as the XML format is unchanged for many years.
Version 6.00 is a major rewrite of the script to use EC JSON data instead of the deprecated XML citypage data for forecasts/alerts. The new alert display mimics that display available on the EC website with a bar for each alert that has clickable areas to expand the details of the alert as a dropdown. The $alertstring variable has the HTML and JavaScript to enable this new display.
