Setting Up Couchbase as a PHP Session Handler with igbinary Encoding

PHP SDK
7

With PHP SDK 4.1.6, I’m able to use ignbinary with this Transcoder. flags are ignored.


<?php
declare(strict_types=1);
namespace Couchbase;
class IgbinaryTranscoder implements Transcoder
{
    private static ?IgbinaryTranscoder $instance;

    public static function getInstance(): Transcoder
    {
        if (!isset(self::$instance)) {
            self::$instance = new IgbinaryTranscoder();
        }
        return self::$instance;
    }

    /**
     *
     * @param mixed $value document
     *
     * @return array tuple of encoded value with flags for network layer
     */
    public function encode($value): array
    {
        return [
            igbinary_serialize($value), 0
        ];
    }

    /**
     *
     * @param string $bytes encoded data
     * @param int $flags flags from network layer, that describes format of the encoded data
     *
     * @return mixed decoded document
     */
    public function decode(string $bytes, int $flags)
    {
        return igbinary_unserialize($bytes);
    }
}

calling code is

	$tx = IgbinaryTranscoder::getInstance();

	$uoptions = new UpsertOptions();
	$uoptions->transcoder($tx);
        $ret = $collection->upsert($key, '{"test":"test"}', $uoptions);

	$options = new GetOptions();
	$options->transcoder($tx);
        $ret = $collection->get($key, $options);
        print($ret->content());
