私はphp IMAP APIを書いています。コンストラクターは Gmail サーバーに接続し、ソケットを変数に格納します。別のメソッドで同じソケット接続を使用すると、接続が null になります。なぜこれが起こり、どうすれば修正できますか?

class Imap{

    const RESPONSE_SIZE = 4096;
    const LOCAL_HOST = '127.0.0.1';
    const CRLF = "\r\n";

    //------------RESPONSE CODES---------//
    const OK = "OK";
    const BAD = "BAD";
    const NO = "NO";

    //----------------FLAGS--------------//
    const FLAG_ANSWERED = "\\Answered";
    const FLAG_FLAGGED = "\\Flagged";
    const FLAG_DRAFT = "\\Draft";
    const FLAG_DELETED = "\\Deleted";
    const FLAG_SEEN = "\\Seen";

    //------------- PRIVATE VARS ------------//
    private $_connection = NULL;
    private $_number = 0;
    private $_instruction_num;

    private $_connected = false;
    private $_authenticated = false;

    //------------- PUBLIC VARS ------------//

    public $error = array();

    function __construct($imap_server, $imap_port)
    {
        $this->connect($imap_server,$imap_port);
    }

    function __destruct()
    {
        if($this->_connected)
            $this->logout();
    }

    private function connect($imap_server, $imap_port)
    {
        if($this->_connected == false)
        {
            if($imap_server == NULL)    $imap_server = self::LOCAL_HOST;
            if($imap_port == NULL)      $imap_port = 993;

            $this->_connection = fsockopen($imap_server,$imap_port);

            if(empty($this->_connection))
            {
                throw new Exception('Connection to server could not be established');
            }
            else $this->_connected = true;      

        }

        return $this->_connected;
    }

    function login($username, $password)
    {
        echo 'connection: '.$this->_connected;
        if(!$this->_authenticated)
        {
            $instruction = $this->get_instruction_num();
            fputs($this->_connection,"$instruction LOGIN $username $password".self::CRLF);
            $response = $this->get_response($instruction);

            switch ($response['code']) {
                case self::OK:
                    $this->_authenticated = true;
                    break;

                case self::NO:
                    $this->_authenticated = false;
                    $this->error = array('error'=>'Invalid username or password.');
                    break;

                case self::BAD:
                default: 
                    $this->_authenticated = false;
                    $this->error = array('error'=>$response['response']);
                break;
            }
        }

        return $this->_authenticated;
    }

private function get_response($aInstructionNumber)
    {

        $end_of_response = false;

        if(empty($this->_connection))
            die('DEAD');//connection is null here.

        while (!$end_of_response)
        {
            $line = fgets($this->_connection,self::RESPONSE_SIZE);
            $response .= $line.'<br/>';

            if(preg_match("/$aInstructionNumber (OK|NO|BAD)/", $response,$responseCode))
                $end_of_response = true;
        }

        return array('code' => $responseCode[1],
            'response'=>$response);
    }

Mailer.php で使用

class Mailer
{
    const imap_server = "ssl://imap.gmail.com";
    const imap_port = 993;
    const smtp_server = "ssl://smtp.gmail.com";
    const smtp_port = 465;

    private $imap = NULL;
    private $smtp = NULL;
    private $username = "";
    private $password = "";

    private $logged_in = false;

    function __construct()
    {
        try{
            $this->imap = new Imap(self::imap_server,self::imap_port);
            $this->smtp = new Smtp(self::smtp_server,self::smtp_port);
        }catch(Exception $e)
        {
            throw new Exception($e->getMessage());
        }
    }

    function login($username,$password)
    {
        if($username != NULL) $this->username = $username;
        if($password != NULL) $this->password = $password;

        //$this->imap = new Imap(self::imap_server,self::imap_port);
        if(!$this->imap->login($this->username,$this->password))
        {
            $result = array('success'=>0,'message'=>$this->imap->error());
        }
        else
        {
            $this->logged_in = true;
            $result = array('success'=>1,'message'=>'Login successful');
        }

        return $result;
    }

ログインページのコード:

    if(!isset($_SESSION['mailer']))
{
    try{
        $mailer = new Mailer();
    }catch(Exception $e){
        die($e->getMessage());
    }

    $_SESSION['mailer'] = serialize($mailer);
}

if(isset($_POST['username']) && isset($_POST['password']))
{
    //ENCRYPT
    $username = htmlentities($_POST['username']);
    $password = htmlentities($_POST['password']);
    $s_mailer = $_SESSION['mailer'];
    $mailer = unserialize($s_mailer);

    $_login = $mailer->login($username,$password);
    if($_login['success']!=1)
    {
        $feedback = $_login['message'];
    }else
        header('Location: inbox.php');      

}

Mailer クラスを SESSION に保存しており、接続がいくつかのリクエスト間で維持されることを期待しています。これは機能しないことに注意してください。

代わりに、シリアル化された Mailer オブジェクトを SESSION に格納し、__sleep と __wakeupを実装してunserializeで接続を再度確立することができます。
