    <p>I found this question on here: <a href="https://stackoverflow.com/questions/927566/php-soap-issue-server-was-unable-to-process-request-object-reference-not-s">PHP Soap Issue: Server was unable to process request. ---&gt; Object reference not set to an instance of an object</a></p> <p>I have a similar issue, only the WSDL is private, so I figured I'd try and get a basic timezone SOAP Client working.</p> <p>The solution in the other question isn't possible for me to use with the private WSDL.</p> <pre><code>$response = $client-&gt;getTimeZoneTime(array('timezone'=&gt;'ZULU')); </code></pre> <p>Really what I need is a way of taking a multidimensional PHP array and putting it into the SOAP formed XML document, without it going crazy and producing stuff like, for this example, this:-</p> <pre><code>&lt;key&gt;GetTimeZoneTime&lt;/key&gt; &lt;item&gt;ZULU&lt;/item&gt; </code></pre> <p>Here's my PHP:</p> <pre><code>try { $WSDL = 'http://www.nanonull.com/TimeService/TimeService.asmx?WSDL'; $client = new SoapClient($WSDL, array( "trace" =&gt; 1, "exceptions" =&gt; 1, "soap_version" =&gt; SOAP_1_1 )); $xml = '&lt;GetTimeZoneTime&gt;&lt;timezone&gt;ZULU&lt;/timezone&gt;&lt;/GetTimeZoneTime&gt;'; $xmlvar = new SoapVar( $xml, XSD_ANYXML ); $response = $client-&gt;getTimeZoneTime($xmlvar); echo "&lt;pre&gt;\n"; echo "Request :\n".htmlspecialchars($client-&gt;__getLastRequest()) ."\n"; echo "Response:\n".htmlspecialchars($client-&gt;__getLastResponse())."\n"; echo "&lt;/pre&gt;"; } catch (SoapFault $exception) { echo "&lt;pre&gt;\n"; echo "Request :\n".htmlspecialchars($client-&gt;__getLastRequest()) ."\n"; echo "Response:\n".htmlspecialchars($client-&gt;__getLastResponse())."\n"; echo $exception; echo "&lt;/pre&gt;"; } </code></pre> <p>This is the request it produces:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://www.Nanonull.com/TimeService/"&gt; &lt;SOAP-ENV:Body&gt; &lt;GetTimeZoneTime&gt; &lt;timezone&gt;ZULU&lt;/timezone&gt; &lt;/GetTimeZoneTime&gt; &lt;/SOAP-ENV:Body&gt; &lt;/SOAP-ENV:Envelope&gt; </code></pre> <p>And the SOAP Fault is:</p> <pre><code>Server was unable to process request. ---&gt; Object reference not set to an instance of an object. </code></pre> <p>What's the correct way of turning a multidimensional PHP array into the appropriate format for a SOAP request?</p> <p>What does the SOAP fault returned actually mean?</p> <p><strong>Edit:</strong> After some searching around elsewhere I thought I'd try the approach of creating a PHP class to mirror the variables on the server. This doesn't work either.</p> <pre><code>class TimeZone { public function __construct () { $this-&gt;timezone = 'ZULU'; } } $WSDL = 'http://www.nanonull.com/TimeService/TimeService.asmx?WSDL'; $client = new SoapClient($WSDL, array( "trace" =&gt; 1, "exceptions" =&gt; 1, "soap_version" =&gt; SOAP_1_1 )); $xmlvar = new SoapVar(new TimeZone(), SOAP_ENC_OBJECT, "TimeZone"); $response = $client-&gt;getTimeZoneTime($xmlvar); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
