I try to use symfony 3.0 Memcached session instead of default one.

I configured my config.yml like this:

imports:
    - { resource: params.php }
    - { resource: security.yml }
    - { resource: services.yml }

# Put parameters here that don't need to change on each machine where the app is deployed
# http://symfony.com/doc/current/best_practices/configuration.html#application-related-configuration
parameters:
    locale: en

framework:
    #esi:             ~
    #translator:      { fallbacks: ["%locale%"] }
    secret:          "%secret%"
    router:
        resource: "%kernel.root_dir%/config/routing.yml"
        strict_requirements: ~
    form:            ~
    csrf_protection: ~
    validation:      { enable_annotations: true }
    #serializer:      { enable_annotations: true }
    templating:
        engines: ['twig']
        #assets_version: SomeVersionScheme
    default_locale:  "%locale%"
    trusted_hosts:   ~
    trusted_proxies: ~
    session:
        # http://symfony.com/doc/current/reference/configuration/framework.html#handler-id
        handler_id:  session.handler.memcached
        session_memcached_host:     127.0.0.1
        session_memcached_port:     11211
        session_memcached_prefix:   ng_
        session_memcached_expire:   43200

# Twig Configuration

    debug:            "%kernel.debug%"
    strict_variables: "%kernel.debug%"

# Doctrine Configuration
doctrine:
    dbal:
        driver:   "%database_driver%"
        host:     "%database_host%"
        port:     "%database_port%"
        dbname:   "%database_name%"
        user:     "%database_user%"
        password: "%database_password%"
        charset:  UTF8
        # if using pdo_sqlite as your database driver:
        #   1. add the path in parameters.yml
        #     e.g. database_path: "%kernel.root_dir%/data/data.db3"
        #   2. Uncomment database_path in parameters.yml.dist
        #   3. Uncomment next line:
        #     path:     "%database_path%"

    orm:
        auto_generate_proxy_classes: "%kernel.debug%"
        naming_strategy: doctrine.orm.naming_strategy.underscore
        auto_mapping: true

# Swiftmailer Configuration
swiftmailer:
    transport: "%mailer_transport%"
    host:      "%mailer_host%"
    username:  "%mailer_user%"
    password:  "%mailer_password%"
    encryption: "%mailer_encryption_method%"
    port: "%mailer_port%"
    spool:     { type: memory }

And I edited the services.yml like that:

services:
    session.memcached:
        class: Memcached
        arguments:
            persistent_id: %session_memcached_prefix%
        calls:
            - [ addServer, [ %session_memcached_host%, %session_memcached_port% ]]

    session.handler.memcached:
        class:     Symfony\Component\HttpFoundation\Session\Storage\Handler\MemcachedSessionHandler
        arguments: ["@session.memcached", { prefix: %session_memcached_prefix%, expiretime: %session_memcached_expire% }

But on the network I get error 500. The reason is because I this line is malformed:

arguments: ["@session.memcached", { prefix: %session_memcached_prefix%, expiretime: %session_memcached_expire% }

How I will give correcttrly the setting for memcached session on Symfony 3?

EDIT 1:

My error.log says:

Edit 2:

Also there is a new config.yml after a few comments suggested in coomments.

    - { resource: params.php }
    - { resource: security.yml }
    - { resource: services.yml }

    session_memcached_expire:   43200

phpsessionmemcachedsymfony
please post the full error displayed. BTW in the config.yml the keys under session named session_memcached_* are parameters so put it under the parameters key in the config.yml – Matteo

In the end the line that causes the problem should be:

arguments: ["@session.memcached", { prefix: %session_memcached_prefix%, expiretime: %session_memcached_expire% }]

(The ] at the end of the entry was missing)
