Constructor __construct (line 163)

Constructor

$config is an instance of Zend_Config or an array of key/value pairs containing configuration options for Zend_Session_SaveHandler_DbTable and Zend_Db_Table_Abstract. These are the configuration options for Zend_Session_SaveHandler_DbTable:

primaryAssignment => (string|array) Session table primary key value assignment (optional; default: 1 => sessionId) You have to assign a value to each primary key of your session table. The value of this configuration option is either a string if you have only one primary key or an array if you have multiple primary keys. The array consists of numeric keys starting at 1 and string values. There are some values which will be replaced by session information:

sessionId => The id of the current session sessionName => The name of the current session sessionSavePath => The save path of the current session

NOTE: One of your assignments MUST contain 'sessionId' as value!

modifiedColumn => (string) Session table last modification time column

lifetimeColumn => (string) Session table lifetime column

dataColumn => (string) Session table data column

lifetime => (integer) Session lifetime (optional; default: ini_get('session.gc_maxlifetime'))

overrideLifetime => (boolean) Whether or not the lifetime of an existing session should be overridden (optional; default: false)
