Prerequisites

You can choose what cache implementation you want to use. This package expects some PSR implementations to be present in order to be installed:

• PSR-6: psr/cache-implementation like symfony/cache or cache/*

Example:

$ composer require symfony/cache

Installation

composer install php-soap/cached-engine

Engines

This package provides engines that can be used in a generic way:

CachedEngine

You can cache a complete engine so that you don't have to reload a WSDL on every HTTP request.

use PhpSoap\CachedEngine\CachedEngine;
use Soap\CachedEngine\CacheConfig;
use Soap\Engine\Engine;

$engine = new CachedEngine(
    $yourPsr6CachePool,
    new CacheConfig(
        key: 'cached-engine',
        ttlInSeconds: 3600 
    ),
    static function (): Engine {
        return new YourSoapEngine();
    }
);

Note: This driver doesn't work well with the LazyEngine because of its closures that cannot be serialized. Since this engine is already lazy, you can use it as a direct replacement.

Drivers

This package provides drivers that can be used in a generic way:

CachedDriver

You can cache a complete driver so that you don't have to reload a WSDL on every HTTP request.

use PhpSoap\CachedEngine\CachedDriver;
use Soap\CachedEngine\CacheConfig;
use Soap\Driver\Driver;

$driver = new CachedDriver(
    $yourPsr6CachePool,
    new CacheConfig(
        key: 'cached-engine',
        ttlInSeconds: 3600 
    ),
    static function (): Driver {
        return new YourSoapDriver();
    }
);

Concrete example:

use Soap\CachedEngine\CacheConfig;
use Soap\CachedEngine\CachedDriver;
use Soap\Encoding\Driver;
use Soap\Wsdl\Loader\StreamWrapperLoader;
use Soap\WsdlReader\Wsdl1Reader;
use Symfony\Component\Cache\Adapter\RedisAdapter;

$driver = new CachedDriver(
    new RedisAdapter(
        RedisAdapter::createConnection('redis://localhost')
    ),
    new CacheConfig('your-soap-driver', ttlInSeconds: 3600),
    static fn() => Driver::createFromWsdl1(
        (new Wsdl1Reader(
            new StreamWrapperLoader()
        ))($wsdlLocation)
    )
);
