The implemented Soap server is provided to the client for calling the function, accept the parameters passed by the client, and
The processing result is returned to the client. The function functions as the sum of the returned parameters. the specific code for file name soapServer. php is as follows:
  /**
* @ Soap instance 2 Server example
* @ Author PHP technology blog, PHP blog, WWW. PHPCQ. COM
*/
Function soap_add ($ num1, $ num2 ){
If (trim ($ num1 )! = (Int) $ num2 | trim ($ num2 )! = (Int) $ num2 ){
Return new SoapFault ('1', 'invalid user data! ');
} Else {
Return $ num1 + $ num2;
}
}
$ SoapServer = new SoapServer (null, array ('URL' => 'Soap '); // Create a SoapServer object
$ SoapServer-> addFunction ('soap _ add'); // register a service function
$ SoapServer-> handle (); // process and generate Soap
The above code compiled a soap_add function to implement the sum of two parameters, and the page supports remote calls from the client.

Client compilation
/**

*/
Try {

// Create a client instance
$ SoapClient = new SoapClient (null,
Array ('location' => 'http: // www.phpcq.com/soapServer.php ',
'URL' => 'Soap '));
$ Num1 = 1; $ num2 = 2;
$ Sum = $ soapClient-> soap_add ($ num1, $ num2 );
Echo $ num1 + $ num2 = $ sum;
} Catch (SoapFault $ fault ){
Echo "error [$ fault-> faultcode: $ fault-> faultstring]";
}
The client code uses the try... catch () statement to implement possible errors during Soap access to the server.
Output in the appropriate format.
