Why can't my app find the session handler? I get this for an error:
Fatal error: Class 'Session' not found in /Users/Eamon/Sites/index.php on line 2
EDIT 2 (refactored index.php)
Here is my index.php:
<?php
class Session
{
private $savePath;
function open($savePath, $sessionName)
{
$this->savePath = $savePath;
if (!is_dir($this->savePath)) {
mkdir($this->savePath, 0777);
}
return true;
}
function close()
{
return true;
}
function read($id)
{
return (string)@file_get_contents("$this->savePath/sess_$id");
}
function write($id, $data)
{
return file_put_contents("$this->savePath/sess_$id", $data) === false ? false : true;
}
function destroy($id)
{
$file = "$this->savePath/sess_$id";
if (file_exists($file)) {
unlink($file);
}
return true;
}
function gc($maxlifetime)
{
foreach (glob("$this->savePath/sess_*") as $file) {
if (filemtime($file) + $maxlifetime < time() && file_exists($file)) {
unlink($file);
}
}
return true;
}
}
$handler = new Session();
session_set_save_handler(
array($handler, 'open'),
array($handler, 'close'),
array($handler, 'read'),
array($handler, 'write'),
array($handler, 'destroy'),
array($handler, 'gc')
);
// the following prevents unexpected effects when using objects as save handlers
register_shutdown_function('session_write_close');
session_start();
// proceed to set and retrieve values by key from $_SESSION
// set time-out period (in seconds)
$inactive = 600;
// check to see if $_SESSION["timeout"] is set
if (isset($_SESSION["timeout"])) {
// calculate the session's "time to live"
$sessionTTL = time() - $_SESSION["timeout"];
if ($sessionTTL > $inactive) {
session_destroy();
echo "session destroyed;"
}
}
?>
<html>...<html>
<?php
session_destroy();
?>
session.php (I basically copied this from here: http://phpmaster.com/writing-custom-session-handlers/):
EDIT (added the interface as suggested by a below comment).
<?php
interface SessionHandlerInterface
{
public function open($path, $name);
public function read($sessionId);
public function write($sessionId, $data);
public function close();
public function destroy($sessionId);
public function gc($lifetime);
}
class Session implements SessionHandlerInterface {
// implement interfaces here
function open($path, $name) {
$db = new PDO("mysql:host=localhost;dbname=itit", "root", "bonjour3");
$sql = "INSERT INTO session SET session_id =" . $db->quote($sessionId) . ", session_data = '' ON DUPLICATE KEY UPDATE session_lastaccesstime = NOW()";
$db->query($sql);
}
function read($sessionId) {
$db = new PDO("mysql:host=localhost;dbname=itit", "root", "bonjour3");
$sql = "SELECT session_data FROM session where session_id =" . $db->quote($sessionId);
$result = $db->query($sql);
$data = $result->fetchColumn();
$result->closeCursor();
return $data;
}
function write($sessionId, $data) {
$db = new PDO("mysql:host=localhost;dbname=itit", "root", "bonjour3");
$sql = "INSERT INTO session SET session_id =" . $db->quote($sessionId) . ", session_data =" . $db->quote($data) . " ON DUPLICATE KEY UPDATE session_data =" . $db->quote($data);
$db->query($sql)
}
function close() {
$sessionId = session_id();
//perform some action here
}
function destroy($sessionId) {
$db = new PDO("mysql:host=localhost;dbname=itit", "root", "bonjour3");
$sql = "DELETE FROM session WHERE session_id =" . $db->quote($sessionId);
$db->query($sql);
setcookie(session_name(), "", time() - 3600);
}
function gc($lifetime) {
$db = new PDO("mysql:host=localhost;dbname=itit", "root", "bonjour3");
$sql = "DELETE FROM session WHERE session_lastaccesstime < DATE_SUB(NOW(), INTERVAL " . $lifetime . " SECOND)";
$db->query($sql);
}
}
?>
Thanks for any help!
UPDATE
I fixed a few errors...I edited my above code to reflect my changes, however I have a few new errors that need sorting out:
Warning: Wrong parameter count for session_set_save_handler() in /Users/Eamon/Sites/index.php on line 4
Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /Users/Eamon/Sites/index.php:1) in /Users/Eamon/Sites/index.php on line 5
Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /Users/Eamon/Sites/index.php:1) in /Users/Eamon/Sites/index.php on line 5
UPDATE 2
Apparently,
The function session_set_save_handler requires six parameters be passed to it.
I read this here: http://forums.phpfreaks.com/topic/18940-session-set-save-handler-problem/
UPDATE 3
Fixed the above parameter error...just put the session class directly in my index.php (I changed my code above to reflect my changes in index.php). Basically...I have exactly what you see in Example 2 here - http://php.net/manual/en/function.session-set-save-handler.php.
Here is the new error I am getting:
Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /Users/Eamon/Sites/templates/showuser.php:1) in /Users/Eamon/Sites/templates/showuser.php on line 2
Here is showuser.php:
<?php
session_start();
$host="localhost"; // Host name
$uname="root"; // Mysql username
$password="bonjour3"; // Mysql password
$db_name="itit"; // Database name
$tbl_name="users"; // Table name
// Connect to server and select database.
$mysqli = mysqli_connect($host, $uname, $password, $db_name);
$stmt = $mysqli->prepare("SELECT email FROM users WHERE username = ?");
$stmt->bind_param("s", $_SESSION["username"]);
$stmt->execute();
$stmt->bind_result($em);
$stmt->fetch();
?>
<h2>Username - Email</h2>
<div id="userinfo"><? echo $_SESSION["username"] ?> - <? echo $em ?></div>
<?
$stmt->close();
mysqli_close($mysqli);
?>
Again...check the changes I made to index.php (the session.php file no longer exists).
