title: Send SOAP request to NOAA
body: <p>Kind of new to SOAP.  Trying to get weather data from NOAA website.  The first SOAP request shown below works, and returns the latitude and longitude.  The second SOAP request doesn't work.  I am obviously not sending the data correctly.  Can anyone help?  Thank you</p>
  
  <pre><code>&lt;?php
      $wsdl = "http://graphical.weather.gov/xml/DWMLgen/wsdl/ndfdXML.wsdl";
  
      $client = new SoapClient($wsdl,array("trace"=&gt;1,"exceptions"=&gt;0));
  
      $rs = $client-&gt;LatLonListZipCode(98011);
      echo('&lt;pre&gt;'.print_r($rs,1).'&lt;/pre&gt;');
  
      $par=array('latitude'=&gt;39.0000,'longitude'=&gt;-77.0000,'product'=&gt;'time-series','startTime'=&gt;'2004-04-27T12:00','endTime'=&gt;'2004-04-30T12:00','Unit'=&gt;'e','weatherParameters'=&gt;'maxt = TRUE');
  
      $rs = $client-&gt;NDFDgen($par);
      echo('&lt;pre&gt;'.print_r($rs,1).'&lt;/pre&gt;');
