Dopo session_start() mi interrompe lo script

[zacca94]

Utilizzo una mia classe personalizzata per gestire le sessioni nel database

# session.php

class Session {
    var $database;
    
    function Session($database) {        
        $this->database = & $database;
        
        session_set_save_handler(array($this, 'open'),
                                 array($this, 'close'),
                                 array($this, 'read'),
                                 array($this, 'write'),
                                 array($this, 'destroy'),
                                 array($this, 'gc'));
                                 
        $this->startSession();
    }

    function startSession() {
        @session_start();
    }
    
    function deleteSession() {
        @session_destroy();
    }
    
    function open($sessPath, $sessName) {
        return true;
    }

    function close() {
        return true;
    }

    function read($sessId) {
        $query = $this->database->mysqlQuery('readSession', array($sessId), 1);
        if ($this->database->mysqlNumRows()) {
            $dataSession = $this->database->mysqlFetchAssoc();
            return $dataSession['sessData'];
        }
    }

    function write($sessId, $sessData) {
        $query = $this->database->mysqlQuery('writeSession', array($sessId, $sessData, time()));
    }

    function destroy($sessId) {
        $query = $this->database->mysqlQuery('destroySession', array($sessId));
    }

    function gc($sessMaxLifeTime) {
        $query = $this->database->mysqlQuery('deleteSessions', array((time() - SESSION_TIME)));
    }
}

?> 

# index.php

<?php

error_reporting(E_ALL);

class Core {
    function Core() {
        $this->initDatabase();
        $this->initSession();
     }

function initDatabase() {
 /*****/
}

    function initSession() {
                @ob_start();
        require_once(PATH.'includes/server.php');
        require_once(PATH.'includes/session.php');
        $this->session = new Session($this->database);
                echo 1;        
    }
}

non stampa echo 1 dopo aver inizializzato la sessione
