PHP 使用soap有两种方式。
一、用wsdl文件
服务器端。
<?php class service
{
public function HelloWorld()
{
return "Hello";
}
public function Add($a,$b)
{
return $a+$b;
}
}
$server=new SoapServer('soap.wsdl',array('soap_version' => SOAP_1_2));
$server->setClass("service");
$server->handle();
?>
资源描述文件，可以用工具(zend studio)生成。其实就是一个xml文件。
<?xml version="1.0" encoding="UTF-8"?>
<definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://localhost/interface/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" name="soap" targetnamespace="http://localhost/interface/">
<types>
<schema targetnamespace="http://localhost/interface/">
<element name="HelloWorld">
<complextype>
<sequence>
<element name="in" type="xsd:string"></element>
</sequence>
</complextype>
</element>
<element name="HelloWorldResponse">
<complextype>
<sequence>
<element name="out" type="xsd:string"></element>
</sequence>
</complextype>
</element>
<element name="Add">
<complextype>
<sequence>
<element name="in" type="xsd:int"></element>
</sequence>
</complextype>
</element>
<element name="AddResponse">
<complextype>
<sequence>
<element name="out" type="xsd:int"></element>
</sequence>
</complextype>
</element>
</schema>
</types>
<message name="AddRequest"> <part name="a" type="xsd:int"></part>
<part name="b" type="xsd:int"></part>
</message>
<message name="AddResponse">
<part name="c" type="xsd:int"></part>
</message>
<porttype name="TestSoap"> <operation name="Add">
<input message="tns:AddRequest">
<output message="tns:AddResponse"></output>
</operation>
</porttype>
<binding name="soapSOAP" type="tns:TestSoap">
<binding style="document" transport="http://schemas.xmlsoap.org/soap/http"></binding>
<operation name="Add">
<operation soapaction="http://localhost/interface/Add"></operation>
<input>
<output>
<body use="literal" namespace="http://localhost/interface/"></body>
</output>
</operation>
</binding>
<service name="TestSoap">
<port binding="tns:soapSOAP" name="soapSOAP">
<address location="http://localhost/interface/myservice.php"></address>
</port>
</service>
</definitions>
客户端调用
<?php $soap = new SoapClient('http://localhost/interface/soap.wsdl');
echo $soap->Add(1,2);
?>
二、不用wsdl文件
服务器端
<?php class service
{
public function HelloWorld()
{
return "Hello";
}
public function Add($a,$b)
{
return $a+$b;
}
}
$server=new SoapServer(null,array('uri' => "abcd"));
$server->setClass("service");
$server->handle();
?>
客户端
<?php try{
$soap = new SoapClient(null,array(
"location" => "http://localhost/interface/soap.php",
"uri" => "abcd", //资源描述符服务器和客户端必须对应
"style" => SOAP_RPC,
"use" => SOAP_ENCODED
));
echo $soap->Add(1,2);
}catch(Exction $e){
echo print_r($e->getMessage(),true);
}

The above introduces the two modes of webserver, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AMYou should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AMSelect DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
