    <p>I wanted to create a web service with php and zend framework. The server side code is as follow:</p> <p><strong>csiService.php:</strong></p> <pre><code>&lt;?php require_once 'Zend/Loader.php'; require_once 'CSI.php'; $WSDL_URI="http://csi.chemicalseeker.com/csiService.php?WSDL"; if(isset($_GET["WSDL"])) { Zend_Loader::loadClass('Zend_Soap_AutoDiscover'); Zend_Loader::loadClass('Zend_Soap_Wsdl_Strategy_ArrayOfTypeSequence'); $autodiscover = new Zend_Soap_AutoDiscover('Zend_Soap_Wsdl_Strategy_ArrayOfTypeSequence'); $autodiscover-&gt;setBindingStyle(array('style' =&gt; 'document')); $autodiscover-&gt;setOperationBodyStyle(array('use' =&gt; 'literal')); $autodiscover-&gt;setClass('CSI'); $autodiscover-&gt;handle(); } else { Zend_Loader::loadClass('Zend_Soap_Server'); $server = new Zend_Soap_Server($WSDL_URI); $server-&gt;setClass('CSI'); $server-&gt;handle(); } ?&gt; </code></pre> <p>Which includes the <strong>CSI.php</strong>:</p> <pre><code>&lt;?php class CSI { /** * @return string */ function helloWorld() { return("Hello"); } } ?&gt; </code></pre> <p>*<em>I edited the host file, in order to bind the domain "csi.chemicalseeker.com" to 127.0.0.1</em> The WSDL just works well as I visit "http://csi.chemicalseeker.com/csiService.php?WSDL" in my browser:</p> <pre><code>&lt;?xml version="1.0"?&gt; &lt;definitions xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="http://csi.chemicalseeker.com/csiService.php" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap-enc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" name="CSI" targetNamespace="http://csi.chemicalseeker.com/csiService.php"&gt; &lt;types&gt; &lt;xsd:schema targetNamespace="http://csi.chemicalseeker.com/csiService.php"&gt; &lt;xsd:element name="helloWorld"&gt; &lt;xsd:complexType /&gt; &lt;/xsd:element&gt; &lt;xsd:element name="helloWorldResponse"&gt; &lt;xsd:complexType&gt; &lt;xsd:sequence&gt; &lt;xsd:element name="helloWorldResult" type="xsd:string" /&gt; &lt;/xsd:sequence&gt; &lt;/xsd:complexType&gt; &lt;/xsd:element&gt; &lt;/xsd:schema&gt; &lt;/types&gt; &lt;portType name="CSIPort"&gt; &lt;operation name="helloWorld"&gt; &lt;documentation&gt;@return string&lt;/documentation&gt; &lt;input message="tns:helloWorldIn" /&gt; &lt;output message="tns:helloWorldOut" /&gt; &lt;/operation&gt; &lt;/portType&gt; &lt;binding name="CSIBinding" type="tns:CSIPort"&gt; &lt;soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http" /&gt; &lt;operation name="helloWorld"&gt; &lt;soap:operation soapAction="http://csi.chemicalseeker.com/csiService.php#helloWorld" /&gt; &lt;input&gt; &lt;soap:body use="literal" /&gt; &lt;/input&gt; &lt;output&gt; &lt;soap:body use="literal" /&gt; &lt;/output&gt; &lt;/operation&gt; &lt;/binding&gt; &lt;service name="CSIService"&gt; &lt;port name="CSIPort" binding="tns:CSIBinding"&gt; &lt;soap:address location="http://csi.chemicalseeker.com/csiService.php" /&gt; &lt;/port&gt; &lt;/service&gt; &lt;message name="helloWorldIn"&gt; &lt;part name="parameters" element="tns:helloWorld" /&gt; &lt;/message&gt; &lt;message name="helloWorldOut"&gt; &lt;part name="parameters" element="tns:helloWorldResponse" /&gt; &lt;/message&gt; &lt;/definitions&gt; </code></pre> <p>I also wrote a php client file called CSIClient.php and visited it from the browser:</p> <p><strong>CSIClient.php</strong></p> <pre><code>&lt;?php require_once 'Zend/Loader.php'; require_once 'CSI.php'; Zend_Loader::loadClass('Zend_Soap_Client'); $WSDL_URI="http://csi.chemicalseeker.com/csiService.php?WSDL"; $client = new Zend_Soap_Client($WSDL_URI); echo('&lt;pre&gt;'); var_dump($client-&gt;helloWorld()); echo('&lt;/pre&gt;'); ?&gt; </code></pre> <p>The result is expected to be a string with the content of "Hello", but it shows an empty stdObject:</p> <pre><code>object(stdClass)#3 (0) { } </code></pre> <p>I can get the function list and type list via "$client->getFunctions()" and "$client->getTypes()", it means the "CSI" class has been connected to the web service successfully. But the result can not be returned correctly.</p> <p>I've also tried other methods to invoke the web service. I used Flash Builder to call the helloWorld() function, the response from server is as follow:</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://csi.chemicalseeker.com/csiService.php"&gt; &lt;SOAP-ENV:Body&gt; &lt;ns1:helloWorldResponse/&gt; &lt;/SOAP-ENV:Body&gt; &lt;/SOAP-ENV:Envelope&gt; </code></pre> <p>As we can see that the expected result "Hello" is not included in the SOAP envelope either. Did I missed something important or made some mistakes in my code? Help me please if you have a clue. Thank you!</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.
