thekirbster Posted December 23, 2011 Share Posted December 23, 2011 So I've been trying to put together a little weather application using the NOAA's weather feed. The site I am connecting to is http://graphical.weather.gov/xml/ Basically, I'm a newbie when it comes to PHP. I want to code it such that a user can enter a zip code and retrieve a host of climatic data. If any one is familiar with tapping into this database (the NDFD) and could help, I'd be very grateful. Below is the code. I first want to retrieve the latitude and longitude of a given zip code and then, because both coordinates are given as a string, I want to break them up into $Lat and $Lon, respectively, and I've been successful with these specific steps. However, I believe I am running into trouble generating the XML from the $result variable and running into trouble with the subsequent parsing on the XML. I'm thinking the issue is with how I am calling the NuSoap client and associated NDFD server file. Anyways, here's the code, and I'd be very appreciative of any help. Thanks. <?php /* http://sourceforge.net/projects/nusoap/ */require('../lib/nusoap.php'); $getZip = array('zipCodeList' => $_GET['zipCodeList']); try{ $c = new nusoap_client('http://graphical.weather.gov/xml/DWMLgen/wsdl/ndfdXML.wsdl', 'wsdl'); $LatLonList = $c->call('LatLonListZipCode',$getZip); $LatLonStr = $LatLonList; $LatLon = explode(',', $LatLonStr, 2);$Lat = ($LatLon[0]);$Lon = ($LatLon[1]); $parameters = array('product' => 'glance','numDays' => 5,'format' => '24 hourly','latitude' => $Lat, 'longitude' => $Lon); $result = $c->call('NDFDgen', $parameters);}catch (Excepion $ex){/* nuSOAP throws an exception is there was a problem fetching the data */echo 'failed';} /* parse the XML data into a giant data object */try{$xml = new SimpleXMLElement($result);}catch (Exception $ex){/* the XML was probably invalid */die('Failed to parse the XML');} Link to comment Share on other sites More sharing options...
justsomeguy Posted December 23, 2011 Share Posted December 23, 2011 What happens when you run the code? Link to comment Share on other sites More sharing options...
