Question

我正在尝试设置自定义会话处理程序（请参见下面的代码），但是我一直收到错误消息（http://php7test.com/alp-ing/）。有什么建议么？

我得到的错误：警告：未知：无法使用用户定义的保存处理程序写入会话数据。（session.save_path：/ var / lib / php / sessions），位于第0行的“未知”中

public function open ($savepath, $cookiekey) {
    // $this->fw_session_log('info', 'open');
    $this->gc(18800);
    return true;
}

public function close() {
    // $this->fw_session_log('info', 'close');
    return true;
}

public function read ($id) {
    $database = $this-> database();
    if (!$database) return "";
    // $this->fw_session_log('info', 'read');

    // TRUE
    if (!preg_match('/^([0-9a-z]{32,52})$/i', $id)) return "";
    #if (! $res = $database->GetResult('SELECT * FROM '.$this->dbsessiontable.' WHERE sessionid=\''.$id.'\' AND ip=\''.$_SERVER['REMOTE_ADDR'].'\'')) { return false; }
    if (!$res = $database->GetResult('SELECT * FROM ' . $this->dbsessiontable . ' WHERE sessionid=\'' . $id . '\'')) {
        return "";
    }
    $sessiondata = $database->FetchArray($res);
    if (is_null($sessiondata)) {
        return "";
    } else {
        $this->lastaccess = $sessiondata['lastaccess'];
        return base64_decode($sessiondata['value']);
    }
}

public function write ($id, $data) {
    $database = $this-> database();
    if (!$database) return false;
    //$this->fw_session_log('info', 'write');       
    if (!preg_match('/^([0-9a-z]{32,52})$/i', $id)) return false;

    $data = base64_encode($data);

    $database->GetResult('UPDATE ' . $this->dbsessiontable . ' SET value=\'' . $database->escapeString($data) . '\', lastaccess=\'' . time() . '\', ip=\'' . $database->escapeString(Util::remoteIP()) . '\' WHERE sessionid=\'' . $id . '\'');
    if ($database->AffectedRows() > 0) {
        return true;
    }

    $database->GetResult('INSERT INTO ' . $this->dbsessiontable . ' SET value=\'' . $database->escapeString($data) . '\', sessionid=\'' . $id . '\', lastaccess=\'' . time() . '\',  ip=\'' . $database->escapeString(Util::remoteIP()) . '\'');
    if ($database->AffectedRows() > 0) {
        return true;
    }

    return false;
}

public function destroy ($id) {
    $database = $this->database();
    if (!$database) return false;
    //$this->fw_session_log('info', 'destroy');
    $id = preg_replace('/[^0-9a-z]/i', '', $id);
    $database->GetResult('DELETE FROM ' . $this->dbsessiontable . ' WHERE sessionid=\'' . $id . '\'');
    return true;
}

public function gc ($maxlifetime) {
    $database = $this->database();
    if (!$database) return false;
    //$this->fw_session_log('info', 'gc');
    $database->GetResult('DELETE FROM ' . $this->dbsessiontable . ' WHERE lastaccess< \'' . (time() - $maxlifetime) . '\'');
    return true;
}

设置自定义会话处理程序时，我总是收到错误消息
