Session.

Installation

composer require rancoud/session

Informations

By default session is in read only (option read_and_close = 1).
You can specify it using Session::setReadWrite() or Session::setReadOnly()

Session::start() is not needed, but:

Session will automatically start in read only when using get, has, hasKeyAndValue, getAll
Session will automatically start in write mode when using set, remove, getAndRemove, keepFlash, gc, regenerate

How to use it?

Set and get value from $_SESSION

Session::set('key', 'value'); $value = Session::get('key');

Use custom options

// first way Session::setOption('name', 'custom_session_name'); // second way Session::start(['cookie_lifetime' => 1440]); Session::set('key', 'value'); $value = Session::get('key');

With encryption on default php session

Session::useDefaultEncryptionDriver('keyForEncryption'); Session::set('key', 'value'); $value = Session::get('key');

With File driver

Session::useFileDriver(); Session::set('key', 'value'); $value = Session::get('key');

With Database driver (you have to install rancoud/database)

$conf = new \Rancoud\Database\Configurator([ 'engine' => 'mysql', 'host' => '127.0.0.1', 'user' => 'root', 'password' => '', 'database' => 'test_database' ]); $db = new \Rancoud\Database\Database($conf); // for using a current connection Session::useCurrentDatabaseDriver($db); // for creating a new connection //Session::useNewDatabaseDriver($conf); Session::set('key', 'value'); $value = Session::get('key');

With Redis driver (you have to install predis/predis)

$params = [ 'scheme' => 'tcp', 'host' => '127.0.0.1', 'port' => 6379, ]; $redis = new Predis\Client($params); // for using a current connection Session::useCurrentRedisDriver($redis); // for creating a new connection //Session::useNewRedisDriver($params); Session::set('key', 'value'); $value = Session::get('key');

With your own driver implementing SessionHandlerInterface and/or SessionUpdateTimestampHandlerInterface

$driver = new MyCustomDriver(); Session::useCustomDriver($driver); Session::set('key', 'value'); $value = Session::get('key');

Static Variables flash access

Flash data are store in a separate variable.
They will dissapear at the end of the script execution or after commit() unsaved().
You can use keepFlash for saving it in $_SESSION.
When flash data is restore, it will be delete in $_SESSION.
