PHP Web Services Using WSDL Step By Step Tutorial - Part 2: Now, we will look sample WSDL document. In this sample, we want to load text from server. User put their name (such as "Aqila"), then server return text "hello, Aqila". Our web services named "hello". Below our WSDL for hello:
<?xml version="1.0"?>
<definitions name="HelloWorld" targetNamespace="urn:HelloWorld" xmlns:tns="urn:HelloWorld" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns="http://schemas.xmlsoap.org/wsdl/">
<types>
<xsd:schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="urn:Hello">
<xsd:element name="getName" type="xsd:string" />
<xsd:element name="HelloResponse" type="xsd:string" />
</xsd:schema>
</types>
<message name="doHello">
<part name="yourName" type="tns:getName" />
</message>
<message name="doHelloResponse">
<part name="return" type="tns:HelloResponse" />
</message>
<portType name="HelloPort">
<operation name="doHello">
<input message="tns:doHello" />
<output message="tns:doHelloResponse" />
</operation>
</portType>
<binding name="HelloBinding" type="tns:HelloPort">
<soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http" />
<operation name="doHello">
<soap:operation soapAction="urn:HelloAction" />
<input>
<soap:body use="encoded" namespace="urn:Hello" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" />
</input>
<output>
<soap:body use="encoded" namespace="urn:Hello" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" />
</output>
</operation>
</binding>
<service name="HelloService">
<port name="HelloPort" binding="tns:HelloBinding">
<soap:address location="http://localhost/test/wsdl/hello_server.php" />
</port>
</service>
</definitions>
Create a file named "hello.wsdl" within www/test/wsdl. Enter code above.
From the code, you can see structure like previous article.
