Installation

composer require byjg/soap-server

Quick Start

Using PHP Attributes (Recommended)

<?php

use ByJG\SoapServer\Attributes\{SoapService, SoapOperation, SoapParameter};
use ByJG\SoapServer\SoapAttributeParser;
use ByJG\SoapServer\ResponseWriter;

#[SoapService(
    serviceName: 'CalculatorService',
    namespace: 'http://example.com/calculator',
    description: 'A simple calculator web service'
)]
class Calculator
{
    #[SoapOperation(description: 'Adds two numbers together')]
    public function add(
        #[SoapParameter(description: 'First number')] int $a,
        #[SoapParameter(description: 'Second number')] int $b
    ): int {
        return $a + $b;
    }

    #[SoapOperation(description: 'Subtracts second from first')]
    public function subtract(int $a, int $b): int
    {
        return $a - $b;
    }
}

// Start the service
$handler = SoapAttributeParser::parse(Calculator::class);
$response = $handler->handle();
ResponseWriter::output($response);

Using Programmatic Configuration

<?php

use ByJG\SoapServer\{SoapHandler, SoapOperationConfig, SoapParameterConfig, SoapType};
use ByJG\SoapServer\ResponseWriter;

$addOperation = new SoapOperationConfig();
$addOperation->description = 'Adds two numbers';
$addOperation->args = [
    new SoapParameterConfig('a', SoapType::Integer),
    new SoapParameterConfig('b', SoapType::Integer)
];
$addOperation->returnType = SoapType::Integer;
$addOperation->executor = function(array $params) {
    return $params['a'] + $params['b'];
};

$handler = new SoapHandler(
    soapItems: ['add' => $addOperation],
    serviceName: 'CalculatorService'
);
$response = $handler->handle();
ResponseWriter::output($response);

Running the Service

Start PHP's built-in web server:

php -S localhost:8080 calculator.php

Then access:

• Service Documentation: http://localhost:8080
• WSDL: http://localhost:8080?wsdl
• DISCO: http://localhost:8080?DISCO

Running Tests

composer install
composer test

Running Static Analysis

composer psalm
