Configuring session storage to use multiple memcached servers

What I did was the following

First add a helpers file app/Http/helpers.php and add to your composer

    "autoload": {
    ...
        "files": [
            "app/Http/helpers.php"
        ]
    }

In app/Http/helpers.php

/**
 * Return the environment specific list of memcached servers
 */
function memcachedServers()
{
    if (env('APP_ENV') == 'local') {
        return [
            [
                'host' => '127.0.0.1', 'port' => 11211, 'weight' => 100,
            ],
        ];
    }

    if (env('APP_ENV') == 'development') {
        return [
            ['host' => '127.0.0.1', 'port' => 11211, 'weight' => 100],
            ['host' => '127.0.0.2', 'port' => 11211, 'weight' => 100],
        ];
    }

    if (env('APP_ENV') == 'production') {
        return [
            [
                'host' => '127.0.0.1', 'port' => 11211, 'weight' => 100,
            ],
        ];
    }

}

In config/cache.php

        'memcached' => [
            'driver'  => 'memcached',
            'servers' => memcachedServers()
        ],

I think you're just re-inventing Laravel's environment system here.

Rather than do this, just create

config/local/cache.php config/production/cache.php etc

and then have

return array(
    'memcached' => array(
        array('host' => '127.0.0.1', 'port' => 11211, 'weight' => 100),
    ), 
);

etc. in each one.

@harhoo "local" and "production" sub-folders does not work with Laravel 5 !

I wrote this small package that allows to load multiple Memcached server configuration from the .env file. I hope it helps ;)
