Version 1.01 - 16-Aug-2006 - added cacheing for RSS feed
Version 1.02 - 08-Dec-2007 - added time formatting for lastBuildDate
Version 1.03 - 17-Dec-2007 - added safety features from Mike Challis - http://www.642weather.com/weather/scripts.php
                             fixed XHTML 1.0-Strict output, improved debug code,
                             added file-mode include functions
Version 1.04 - 22-Jan-2008 - added graceful failure code from Mike Challis
Version 1.05 - 27-Jan-2008 - added many features from Mike Challis, rename to rss-advisory.php
                             accommodates a different CSS style for when there is no advisory,
                             backwards compatible with old include methods if you are not going to use the
                             CSS style switch for no advisory / advisory
                             NOTE: to use the new feature (CSS style switch for no advisory / advisory)
                             use the new php include params and add the sample css (see settings notes),
                             added invalid zone error code
                             added option to lowercase the advisories text
Version 1.06 - 02-Feb-2008 - added wxflyer.php support from Mike Challis.
                             see: http://www.weather-watch.com/smf/index.php/topic,28523.0.html
                             when used for a printable flyer, advisory titles are shown without URL links
                             Live example: http://www.642weather.com/weather/local-flier.php
                             (the live example only shows advisories when they are currently active)
Version 1.07 - 04-Feb-2008 - added support for Carterlake/AJAX/PHP template set
Version 1.08 - 17-Mar-2008 - added improved cache file error handling
Version 2.00 - 31-May-2009 - beta version specific to new beta NWS feeds
                             http://www.weather.gov/alerts-beta/
                             modded by Mike Challis - http://www.642weather.com/weather/scripts.php
                             (not backwards compatible with old feeds, requires PHP5)
                             see: http://www.weather-watch.com/smf/index.php/topic,40119.0.html
Version 2.00 - 31-Aug-2009   No longer BETA
Version 2.01 - 21-Sep-2009   Renamed at atom-advisory.php to avoid confusion and allow coexistance with
                             rss-advisory.php which used the RSS feeds instead of the ATOM/CAP feeds.
Version 2.02 - 22-Sep-2009   Changed to use HTTP/1.1 requests
Version 2.03 - 29-Oct-2009   Added County zone code capability (M Challis)
Version 2.04 - 28-Jan-2010   Fixed unterminated entity reference error (M Challis)

/*

This script gets the current ATOM/CAP Zone Watch/Warning/Advisory/Statement
from www.weather.gov/alerts-beta/ for the selected Zone and provides either
a summary (titles only, with links) or details.  It returns
'There are no active watches, warnings or advisories for zone CAZ513'
if there are no cited hazards in the Zone CAZ513.

output: creates XHTML 1.0-Strict HTML page (default)

Options on URL:
inc=Y           -- returns only the body code for inclusion in other webpages.  Omit to return full HTML.
summary=Y       -- returns only the titles of the cited hazards N.N or greater.
zone=ssZnnn     -- select the Zone to use.
   Pick the Zone from the RSS feed list at http://www.weather.gov/alerts/
   and use the RSS County/Zone for your area.
detailpage=xxx   -- set your page of full advisories ie: detailpage=advisories.php
cache=refresh    -- reload the cache

Example URL:
http://your.website/atom-advisory.php?zone=CAZ513
  would return data for hazards in Zone=CAZ513 which is Santa Clara County, California

#########
# PHP Include Usage:
#########
You can include this with summary output only
or you can include it with full advisory text output:

There are two ways of including the script in your pages depending on whether your hoster has
allow_url_include option set to on or off. The URL method only works if allow_url_fopen
is on in your PHP settings. The File method usually always works.

#########
# Include and display alert links only, not full alert details:
# Live example: http://www.642weather.com/weather/index.php
#########
to include this with Summary output only, put the following code in your php page inside php tags:

if ( isset($_GET['zone']) ) {
   $DefaultZone = $_GET['zone'];
} else {
   $DefaultZone = 'WAZ021'; // set to your NOAA zone
}
$detailpage  = 'advisories.php'; // overrides $hurlURL setting
$doSummary   = 1;  // display alert links only, not full alert details
$includeOnly = 1;  // include mode
$noprint     = 1;  // required for echo $advisory_html output
include 'originals-nonphp8/atom-advisory.php';
if (preg_match("|There are no active|i",$advisory_html) ||
   preg_match("|Advisory Information Unavailable|i",$advisory_html)) {
   echo '<div class="advisoryBoxnoactive">' .$advisory_html .'</div>';
}else{
   echo '<div class="advisoryBox">' . $advisory_html .'</div>';
}

#########
# Include and display full alert details::
# Live example: http://www.642weather.com/weather/advisories.php
#########
to include this with Full advisory output, put the following code in your php page inside php tags:

if ( isset($_GET['zone']) ) {
   $DefaultZone = $_GET['zone'];
} else {
   $DefaultZone = 'WAZ021'; // set to your NOAA zone
}
$detailpage  = 'advisories.php'; // overrides $hurlURL setting
$includeOnly = 1;  // include mode
$noprint     = 1;  // required for echo $advisory_html output
include 'originals-nonphp8/atom-advisory.php';
if (preg_match("|There are no active|i",$advisory_html) ||
   preg_match("|Advisory Information Unavailable|i",$advisory_html)) {
   echo '<div class="advisoryBoxnoactive">' .$advisory_html .'</div>';
}else{
   echo $advisory_html;
}

#########
# CSS sample:
#########
put this css style code in your css file (modify the colors if you like)
(no need to worry about this if you use the PHP carterlake templates)
