Question

好吧，这是我第一次在这里问一个问题。我的问题很困难，因为很难找到底线。故事是这样的：我有这个小系统，它发送了很多电子邮件邀请（不是垃圾邮件）。所以，明智的是，我不使用PHP函数mail（），我使用像Mail，Mail_Queue，Net_SMTP等PEAR类。唯一的问题是，我的错误日志填满了大量的错误：

PHP Notice:  Error in sending mail: 
Mail Queue Error: Cannot initialize container in /usr/lib/php/PEAR.php on line 873

然后，当然：

[18-Feb-2011 17:38:44] PHP Fatal error:  
Allowed memory size of 33554432 bytes exhausted 
(tried to allocate 3 bytes) in /usr/lib/php/PEAR.php on line 844

这是进入邮件队列的代码（在名为Newsletter的类中）

//I know passing the DSN as the string is kind of deprecated, 
//but it;'s the only way it works on my system
$dsn ="mysql://$db_user:$db_pass@$db_host/$db_name";
$db_options = array();
$db_options['type']       = 'db';
$db_options['dsn']        = $dsn;
$db_options['mail_table'] = TABLE_QUEUE;

$this->host = '-- valid host here --';//data in these strings has been obscured
$this->username = '-- valid username here --';
$this->password = '-- valid password here --';

//optionally, a 'dns' string can be provided instead of db parameters.
//look at DB::connect() method or at DB or MDB docs for details.
//you could also use mdb container instead db
//$server = isset($_SERVER['SERVER_NAME'])?$_SERVER['SERVER_NAME']:'localhost';
$mail_options = array(
    'driver'   => 'smtp',
    'host'     => $this->host,
    'port'     => 25,
    'auth'     => true,
    'username' => $this->username,
    'password' => $this->password,
);
$this->mail_queue = new Mail_Queue($db_options, $mail_options);

更多代码，

public function sendChunk($start, $count)
{
    global $db;
    $ids = $db->get_results("SELECT DISTINCT id_user as id FROM ".TABLE_QUEUE);
    $ret = array();
    foreach ($ids as $id)
        $ret[] = $id->id;
    unset($ids);        
    $this->mail_queue->sendMailsInQueue($count, $start, 1);
    return true;
}

问题是，我仔细检查了我编写的每一行代码，并且正在完成它的工作。唯一的问题是，有时它拒绝发送任何邮件。提前感谢您的回复。

Answer 1

我切换到MDB2而不是DB

$db_options['type']       = 'db';

到

$db_options['type']       = 'mdb2';

这有助于解决内存耗尽问题，我仍然希望在/usr/lib/php/PEAR.php问题中初始化容器

好的找到容器错误的解决方案：应用此补丁 http://svn.php.net/viewvc/pear/packages/Mail_Queue/trunk/Mail/Queue.php?r1=303876&r2=309126
