如何从远程php服务器访问WCF自托管服务

我使用C#应用程序创建了自托管WCF服务。我想从远程php服务器向C#应用程序发送消息。我该如何执行此功能？

<?xml versio="1.0"?>      
<configuration><system.serviceModel>      
  <services>       
    <service name="MyMathServiceLib.MyMathService" behaviorConfiguration="myMathServiceBehave">       
      <host>       
        <baseAddresses>       
          <add baseAddress="http://localhost:9001/MyMathService"/>       
          <add baseAddress="net.tcp://localhost:9002/MyMathService"/>       
        </baseAddresses>       
      </host>       
      <endpoint address="http://localhost:9001/MyMathService" binding="basicHttpBinding"   contract="MyMathServiceLib.IMyMathService"/>       
      <endpoint address="net.tcp://localhost:9002/MyMathService" binding="netTcpBinding"   contract="MyMathServiceLib.IMyMathService"/>       
      <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>       
      <endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange"/>       
    </service>       
  </services>       
  <behaviors>       
    <serviceBehaviors>       
      <behavior name="myMathServiceBehave">       
        <serviceMetadata httpGetEnabled="true"/>       
      </behavior>       
    </serviceBehaviors>       
  </behaviors>       
</system.serviceModel>       
</configuration>

这是我的app.config文件（参考：http://www.codeproject.com/Articles/650869/Creating-a-Self-Hosted-WCF-Service)

我的目标是将消息从php服务器发送到c#应用程序
