Session Handlers

Collection of Mostly used Session Handlers

• Supports File / MySql / Redis / Memcached / Cookie based Session Handlers
• Supports Readonly mode as well for all the above mentioned Session Handlers

Example

Using Normal session

<?php
include __DIR__ . '/CustomSessionHandler/Session.php';

// Turn on output buffering
ob_start();

// Session Runtime Configuration
$options = [];

// Initialise Session Handler
Session::initSessionHandler('File', $options);
// Session::initSessionHandler('MySql');
// Session::initSessionHandler('Redis');
// Session::initSessionHandler('Memcached');
// Session::initSessionHandler('Cookie');

// Start session in normal (read/write) mode.
Session::start_rw_mode();
$_SESSION['id'] = rand();

Using Read-only mode

<?php
include __DIR__ . '/CustomSessionHandler/Session.php';

// Turn on output buffering
ob_start();

// Session Runtime Configuration
$options = [];

// Initialise Session Handler
Session::initSessionHandler('File', $options);
// Session::initSessionHandler('MySql');
// Session::initSessionHandler('Redis');
// Session::initSessionHandler('Memcached');
// Session::initSessionHandler('Cookie');

// Start session in readonly mode
// Use when user is already logged in and we need to authorise the client cookie.
Session::start_readonly();

if (isset($_SESSION)) {
    print_r($_SESSION);
}

Using Read-only with Normal session

<?php
include __DIR__ . '/CustomSessionHandler/Session.php';

// Turn on output buffering
ob_start();

// Session Runtime Configuration
$options = [];

// Initialise Session Handler
Session::initSessionHandler('File', $options);
// Session::initSessionHandler('MySql');
// Session::initSessionHandler('Redis');
// Session::initSessionHandler('Memcached');
// Session::initSessionHandler('Cookie');

// Start session in readonly mode
// Use when user is already logged in and we need to authorise the client cookie.
Session::start_readonly();

// Auth Check
if (!isset($_SESSION) || !isset($_SESSION['id'])) {
    die('Unauthorised');
}

// Start session in normal (read/write) mode.
// Use once client is authorised and want to make changes in $_SESSION
Session::start_rw_mode();
$_SESSION['id'] = rand();

Database Table for MySql

CREATE TABLE IF NOT EXISTS `sessions` (
    `sessionId` CHAR(64) NOT NULL,
    `lastAccessed` INT UNSIGNED NOT NULL,
    `sessionData` MEDIUMBLOB,
    PRIMARY KEY (`sessionId`)
) ENGINE=InnoDB;
