    <p>Hello i'm trying to understand how sessions work and how does <code>session_set_handler()</code> works, so i've started build a class for session handling but i've encountered some problems with the <code>write()</code> function can you please help me solve the problem?</p> <pre><code>&lt;?php class Session extends Model { public $connectionName = 'sessions', $sessionsId, $sessionsData; public function __construct() { parent::__construct(); session_set_save_handler( array($this, 'Open'), array($this, 'Close'), array($this, 'Read'), array($this, 'Write'), array($this, 'Destroy'), array($this, 'Gc')); session_start(); } public function __destruct() { session_write_close(); } public function Open() { return true; } public function Close() { return true; } public function Read($sessionsId) { $this-&gt;stmt = $this-&gt;prepare("SELECT * FROM `sessions` WHERE `id` = :sessionId"); $this-&gt;stmt-&gt;bindParam(":sessionId", $sessionsId); $this-&gt;stmt-&gt;execute(); return $this-&gt;stmt-&gt;fetchAll(); } public function Write($sessionsId, $sessionsData) { $this-&gt;stmt = $this-&gt;prepare("REPLACE INTO `sessions`.`sessions` (`id`, `access`, `data`) VALUES (:sessionId, NOW(), :sessionValue)"); $this-&gt;stmt-&gt;bindParam(":sessionId", $sessionsId); $this-&gt;stmt-&gt;bindParam(":sessionValue", $sessionsData); $this-&gt;stmt-&gt;execute(); } public function Destroy($sessionsId) { $this-&gt;stmt = $this-&gt;prepare("DELETE FROM `sessions`.`sessions` WHERE `id` = :sessionId"); $this-&gt;stmt-&gt;bindParam(":sessionId", $sessionsId); $this-&gt;stmt-&gt;execute(); } public function Gc() { $this-&gt;stmt = $this-&gt;prepare("DELETE FROM `sessions`.`sessions` WHERE `access` &lt; NOW() - INTERVAL 1 HOUR"); $this-&gt;stmt-&gt;execute(); } } </code></pre> <p>now the above code seems to work just fine the only problem is when i write a session in db i get the following insert:</p> <p>dump from mysql</p> <pre><code>CREATE TABLE IF NOT EXISTS `sessions` ( `id` varchar(32) NOT NULL, `access` datetime NOT NULL, `data` text NOT NULL, UNIQUE KEY `id` (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; INSERT INTO `sessions` (`id`, `access`, `data`) VALUES ('lhig71coed8ur81n85iiovje37', '2011-07-25 15:37:57', ''); </code></pre> <p>As you can see the value of the session it's not inserted i only get the session id. on <code>var_dump($sessionsData)</code> i get:</p> <pre><code>"name|s:6:"Bogdan";" </code></pre> <p>and for <code>var_dump($sessionsId)</code> i get:</p> <pre><code>lhig71coed8ur81n85iiovje37 </code></pre> <p>Can you please help? i don't get any errors checked xampp logs setup display errors on error reporting everything i knew even in php.ini still no error anything used even try catch blocks. thank you very much for reading this and helping me out.</p>

    1. COCan you confirm if $sessionsData does have values? Try echoing it before processes.

    2. COThat var_dump looks suspicious. It's not valid `serialize()` output - is there any HTML/xml stored in the session array that might be getting "hidden" by a browser view? What do you see in the browser's view-source?

    3. CO@Marc B: The `var_dump` looks really well for session data. `serialize()` does not work properly with session data, I think you mix this a bit because it's close, but session data is [a list of variable names with their serialized values](http://stackoverflow.com/questions/6722874/what-is-the-php-binary-serialization-handler/6723154#6723154) like so `({varname}|{serialized($varname)})*`.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
