Zend\Session

Session Config

Zend Framework comes with a standard set of config classes which are ready for you to use. Config handles setting various configuration such as where a cookie lives, lifetime, including several bits to configure ext/session when using Zend\Session\Config\SessionConfig.

Standard Config

Zend\Session\Config\StandardConfig provides you a basic interface for implementing sessions when not leveraging ext/session. This is utilized more for specialized cases such as when you might have session management done by another system.

Basic Configuration Options

The following configuration options are defined by Zend\Session\Config\StandardConfig.

Option Data Type Description
cache_expire integer Specifies time-to-live for cached session pages in minutes.
cookie_domain string Specifies the domain to set in the session cookie.
cookie_httponly boolean Marks the cookie as accessible only through the HTTP protocol.
cookie_lifetime integer Specifies the lifetime of the cookie in seconds which is sent to the browser.
cookie_path string Specifies path to set in the session cookie.
cookie_secure boolean Specifies whether cookies should only be sent over secure connections.
entropy_length integer Specifies the number of bytes which will be read from the file specified in entropy_file.
entropy_file string Defines a path to an external resource (file) which will be used as an additional entropy.
gc_maxlifetime integer Specifies the number of seconds after which data will be seen as ‘garbage’.
gc_divisor integer Defines the probability that the gc process is started on every session initialization.
gc_probability integer Defines the probability that the gc process is started on every session initialization.
hash_bits_per_character integer Defines how many bits are stored in each character when converting the binary hash data.
name string Specifies the name of the session which is used as cookie name.
remember_me_seconds integer Specifies how long to remember the session before clearing data.
save_path string Defines the argument which is passed to the save handler.
use_cookies boolean Specifies whether the module will use cookies to store the session id.

Basic Usage

A basic example is one like the following:

use Zend\Session\Config\StandardConfig;
use Zend\Session\SessionManager;

$config->setOptions(array(
    'remember_me_seconds' => 1800,
    'name'                => 'zf2',
));
$manager = new SessionManager($config);

Session Config

Zend\Session\Config\SessionConfig provides you a basic interface for implementing sessions when that leverage PHP’s ext/session. Most configuration options configure either the Zend\Session\Storage OR configure ext/session directly.

Basic Configuration Options

The following configuration options are defined by Zend\Session\Config\SessionConfig, note that it inherits all configuration from Zend\Session\Config\StandardConfig.

Option Data Type Description
cache_limiter string Specifies the cache control method used for session pages.
hash_function string Allows you to specify the hash algorithm used to generate the session IDs.
php_save_handler string Defines the name of a PHP save_handler embedded into PHP.
serialize_handler string Defines the name of the handler which is used to serialize/deserialize data.
url_rewriter_tags string Specifies which HTML tags are rewritten to include session id if transparent sid enabled.
use_trans_sid boolean Whether transparent sid support is enabled or not.

Basic Usage

A basic example is one like the following:

1

use Zend\Session\Config\SessionConfig;
use Zend\Session\SessionManager;

$config = new SessionConfig();
$config->setOptions(array(
    'phpSaveHandler' => 'redis',
    'savePath' => 'tcp://127.0.0.1:6379?weight=1&timeout=1',
));
$manager = new SessionManager($config);

Custom Configuration

In the event that you prefer to create your own session configuration; you must implement Zend\Session\Config\ConfigInterface which contains the basic interface for items needed when implementing a session. This includes cookie configuration, lifetime, session name, save path and an interface for getting and setting options.
