Simple file caching for the Guzzle http client

A lightweight file cache for Guzzle 7+ implementing the PSR-16 Caching Interface

How to use

<?php

use GuzzleHttp\Client;
use GuzzleHttp\HandlerStack;
use Peroks\GuzzleFileCache\Cache;
use Peroks\GuzzleFileCache\FileStorage;

function getGuzzleClient( array $options = [] ): Client {
    $stack = HandlerStack::create();
    $store = new FileStorage( 'your/cache/directory' );
    $cache = new Cache( $store );

    $stack->push( $cache );
    $options['handler'] = $stack;

    return new Client( $options );
}

You use an instance of the Peroks\GuzzleFileCache\Cache class to add file-caching as a handler (middleware) to the Guzzle http client.

Peroks\GuzzleFileCache\FileStorage does the real work, implementing the PSR-16: Common Interface for Caching Libraries.

After you have added caching to the Guzzle http client, there is a new option for caching: ttl (time-to-live). The ttl value is in seconds.

You can set this option for each request sent through the client. If you omit this option or set ttl to 0, the request is not cached.

$response = $client->send( $request, [ 'ttl' => 3600 ] ); // 1 hour caching.
