PHP Development WebService
WSO2 WSF/PHP (WSO2 Web Services Framework/PHP, WSO2 Web Services Framework) is a PHP extension that allows Create and use web services. It supports SOAP1.1, SOAP1.2, MTOM, Web service addressing, Web service security, and also supports REST style calls. The latest version of WSO2 WSF/PHP (v2.0.0) has just been released.
The following is a short guide explaining how to create a simple calculator service using the WSO2 WSF/PHP extension.
(Assumption: Apache HTTP server has been installed on your machine, and you are basically familiar with running PHP scripts on the Apache server)
Step 1: Install WSO2 WSF/PHP extension
In Ubuntu Next, there are the following steps:
1. apt-get install php5 2. apt-get install php5-dev 3. apt-get libapache2-mod-php5 3. apt-get install lib xml 2 4. apt-get install libxml2-dev 5. 下载 WSF/PHP v2.0.0 并解压到一个目录 6. 在命令行访问该目录，以“root”执行下列命令： ./configure make make install 7. /etc/init.d/apache2 restart
Step 2: Write the calculator service
Create a script named CalculatorService.php and put it into the web root of the Apache HTTP server (usually / var/www).
<?php
function calculate($inMessage){
$simplexml = new SimpleXMLElement($inMessage->str);
$operand1 = $simplexml->param1[0];
$operand2 = $simplexml->param2[0];
$operation = $simplexml->param3[0];
if($operation != null)
{
switch($operation)
{
case "add" : $result= $operand1 + $operand2; break;
case "sub" : $result= $operand1 - $operand2; break;
case "mul" : $result= $operand1 * $operand2; break;
case "p" : $result= $operand1 / $operand2; break;
}
}
$response = <<<XML
<result>$result</result>
XML;
$returnMsg = new WSMessage($response);
return $returnMsg;
}
$service = new WSService(array("operations" => array("calculate")));
$service->reply();
?>Once deployed, it can be accessed from http://localhost:
Step 3: Write calculator client
Write a client, call this calculator service, and print the results.
The script is named CalculatorClient.php and placed in the web root of the Apache HTTP server.
Don’t forget to change the port of the Apache server (i.e. http://www.php.cn/:81/CalculatorService.php) to match the server.
<?php
$requestPayload = <<<XML
<calculate>
<param1>100</param1>
<param2>43</param2>
<param3>add</param3>
</calculate>
XML;
try{
$message = new WSMessage($requestPayload,
array("to" => "http://localhost:81/CalculatorService.php"));
$client = new WSClient();
$response = $client->request($message);
echo "Answer : $response->str";
}
catch (Exception $e){
if ($e instanceof WSFault){
$fault = $e;
printf("Soap Fault received. Code: '%s' .Reason: '%s'/n",
$fault->code, $fault->reason);
}else{
printf("Exception occurred. Message: '%s'/n", $e->getMessage());
}
}
?>Step 4: Access the service
Access the service by executing CalculatorClient.php, as follows:
http://localhost:

What are the standards for web services?
Nov 30, 2023 pm 05:45 PM
There are seven standards for web services: "HTTP protocol", "RESTful architecture", "data exchange format", "WSDL", "SOAP", "security" and "scalability": 1. HTTP protocol, Web service usage HTTP protocol communicates, so it needs to follow the specifications of the HTTP protocol; 2. RESTful architecture, used to build scalable, loosely coupled Web services; 3. Use a certain data exchange format to transmit data; 4.

Describe the SOLID principles and how they apply to PHP development.
Apr 03, 2025 am 12:04 AM
The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
