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_once __DIR__ . '/Autoload.php';

use CustomSessionHandler\Session;

// Turn on output buffering
ob_start();

// Session Runtime Configuration
$options = [];

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

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

Using Read-only mode

<?php
include_once __DIR__ . '/Autoload.php';

use CustomSessionHandler\Session;

// Turn on output buffering
ob_start();

// Session Runtime Configuration
$options = [];

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

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

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

Using Read-only with Normal session

<?php
include_once __DIR__ . '/Autoload.php';

use CustomSessionHandler\Session;

// Turn on output buffering
ob_start();

// Session Runtime Configuration
$options = [];

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

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

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

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

Switching from previous session to this package based session handler

<?php
include_once __DIR__ . '/Autoload.php';

use CustomSessionHandler\Session;

$prevSessionData = [];
if (isset($_COOKIE['PrevSessCookieName'])) {
    // Load session the was it was used previously in read_and_close mode
    // This will load previous session data in $_SESSION
    session_start(['read_and_close' => true]);

    // Collect previous session data
    $prevSessionData = $_SESSION;
    // Destroy previous session (Note: $_SESSION data will be preserved)
    session_destroy();
}

// Starting below to switch the session mode with current package.
// Turn on output buffering
ob_start();

// Session Runtime Configuration
$options = [];

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

// Start session in normal (read/write) mode.
// Use once client is authorized and want to make changes in $_SESSION
Session::sessionStartReadWrite();

if (!empty($prevSessionData)) {
    $_SESSION = $prevSessionData;
}

// Auth Check with $_SESSION data.
if (!isset($_SESSION) || !isset($_SESSION['id'])) {
    die('Unauthorized');
}

// PHP Code

Database Table for MySql

    `sessionId` CHAR(64) NOT NULL,
    `lastAccessed` INT UNSIGNED NOT NULL,
