我会隐藏到$_SESSION
您使用的项目中。项目应该$_SESSION
像以前一样简单地使用,但您管理读取的数据。也使用你自己的SessionHandler
,这样当一个项目$_SESSION
被破坏时,另一个项目不会。
您应该在开始会话时包含此文件。然后,不要在任何地方使用session_start()
。
class SessionAccess implements ArrayAccess {
protected $handler;
public $session;
public function __construct (SharedSessionHandler $handler) {
$this->handler = $handler;
$this->session = $_SESSION;
if (!isset($this->session[NULL]))
$this->session[NULL] = [];
}
public function __get ($project) {
return $this->session[$project];
}
public function offsetGet ($id) {
return $this->getKey($id)[$id];
}
public function __set ($project, $val) {
$this->session[$project] = $val;
}
public function offsetSet ($id, $val) {
return $this->getKey($id)[$id] = $val;
}
public function __isset ($project) { // don't think it should be used with empty() ...
return isset($this->session[$project]);
}
public function offsetExists ($id) {
return isset($this->getKey($id)[$id]);
}
public function __unset ($project) {
$this->session[$project] = [];
}
public function offsetUnset ($id) {
unset($this->getKey($id)[$id]);
}
protected function &getKey ($id) {
return isset($this->session[NULL][$id])?$this->session[NULL]:$this->session[$this->handler->projectMapper()];
}
}
class SharedSessionHandler extends SessionHandler { // we want to preserve write/read functions etc., only put a thin layer of abstraction between
protected $projects = [];
private $writing = false;
private $tmpSessionStore;
public function registerProject ($project_name, $base) {
$this->projects[$base] = $project_name;
if (!isset($_SESSION->$project_name))
$_SESSION->$project_name = [];
}
public function projectMapper () {
$bt = debug_backtrace(DEBUG_BACKTRACE_IGNORE_ARGS, 3)[2];
foreach ($this->projects as $base => $name) {
if (substr_compare(realpath($base), realpath($bt["file"]), 0, strlen($base)) === 0)
return $name;
}
return NULL;
}
public function write ($session_id, $session_data) {
if (!$this->writing) {
$this->writing = true;
$this->tmpSessionStore = $_SESSION;
$_SESSION = $_SESSION->session;
session_write_close();
} else {
parent::write($session_id, $session_data);
$_SESSION = $this->tmpSessionStore;
$this->writing = false;
}
}
public function close () { // as session_write_close() _will_ trigger this (prevent writing to closed stream)
return true;
}
public function destroy ($session_id) {
$key = $this->projectMapper();
if ($key === null) {
foreach ($this->projects as $project)
unset($_SESSION->$project);
} else {
unset($_SESSION->$key);
}
}
}
session_set_save_handler($sessionHandler = new SharedSessionHandler());
session_start();
$_SESSION = new SessionAccess($sessionHandler);
如果您使用它,您的所有项目都会有一个大型会话。您无需更改任何内容(除了删除所有session_start()
.
我想您的每个项目都在自己的路径中,因此,要区分不同$_SESSION
的 s,请使用:
$sessionHandler->registerProject("projectName", __DIR__); // __DIR__ or the path to the project
要访问您的其他会话,请使用$_SESSION->projectName[$variable]
.
不在任何注册目录中的所有内容都将使用相同的全局会话存储。如果此全局存储中未设置任何密钥,它将从您的本地存储中获取密钥 - 或失败并发出通知。
