    <p>I've written a web service using ASP.NET (in C#) and I'm attempting to write an example PHP client using NuSOAP. Where I'm tripped up on are examples of how to do this; some show <code>soapval</code> being used (and I don't quite understand the parameters - for example passing <code>false</code> as <code>string</code> types, etc.), while others are just using straight <code>array</code>s. Let's say the WSDL for my web service as reported by <code>http://localhost:3333/Service.asmx?wsdl</code> looks something like:</p> <pre><code>POST /Service.asmx HTTP/1.1 Host: localhost Content-Type: text/xml; charset=utf-8 Content-Length: length SOAPAction: "http://tempuri.org/webservices/DoSomething" &lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"&gt; &lt;soap:Body&gt; &lt;DoSomething xmlns="http://tempuri.org/webservices"&gt; &lt;anId&gt;int&lt;/anId&gt; &lt;action&gt;string&lt;/action&gt; &lt;parameters&gt; &lt;Param&gt; &lt;Value&gt;string&lt;/Value&gt; &lt;Name&gt;string&lt;/Name&gt; &lt;/Param&gt; &lt;Param&gt; &lt;Value&gt;string&lt;/Value&gt; &lt;Name&gt;string&lt;/Name&gt; &lt;/Param&gt; &lt;/parameters&gt; &lt;/DoSomething&gt; &lt;/soap:Body&gt; &lt;/soap:Envelope&gt; </code></pre> <p>My first PHP attempt looks like:</p> <pre><code>&lt;?php require_once('lib/nusoap.php'); $client = new nusoap_client('http://localhost:3333/Service.asmx?wsdl'); $params = array( 'anId' =&gt; 3, //new soapval('anId', 'int', 3), 'action' =&gt; 'OMNOMNOMNOM', 'parameters' =&gt; array( 'firstName' =&gt; 'Scott', 'lastName' =&gt; 'Smith' ) ); $result = $client-&gt;call('DoSomething', $params, 'http://tempuri.org/webservices/DoSomething', 'http://tempuri.org/webservices/DoSomething'); print_r($result); ?&gt; </code></pre> <p>Now aside from the Param type being a complex type which I'm pretty sure my simple <code>$array</code> attempt will not automagically work with, I'm breakpointing in my web service and seeing the method I've marked as <code>WebMethod</code> (without renaming it, its literally <code>DoSomething</code>) and seeing the arguments are all default values (the <code>int</code> is <code>0</code>, the <code>string</code> is <code>null</code>, etc.).</p> <p>What should my PHP syntax look like, and what do I have to do to pass the <code>Param</code> type correctly?</p>

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.
