我使用php-imap-client从php-imap获取邮件,脚本工作没有问题,但我想限制从服务器获取的邮件数量。

这是剧本:

<?PHP

require_once "Imap.php";

$mailbox = 'imap-mail.outlook.com';
$username = 'MYEMAIL@outlook.it';
$password = 'MYPASSWORD';
$encryption = 'ssl'; // or ssl or ''

// open connection
$imap = new Imap($mailbox, $username, $password, $encryption);

// stop on error
if($imap->isConnected()===false)
    die($imap->getError());

// get all folders as array of strings
$folders = $imap->getFolders();
foreach($folders as $folder)
    echo $folder;

// select folder Inbox
$imap->selectFolder('INBOX');

// count messages in current folder
$overallMessages = $imap->countMessages();
$unreadMessages = $imap->countUnreadMessages();

// fetch all messages in the current folder
$emails = $imap->getMessages($withbody = false);
var_dump($emails);

// add new folder for archive
$imap->addFolder('archive');

// move the first email to archive
$imap->moveMessage($emails[0]['id'], 'archive');

// delete second message
$imap->deleteMessage($emails[1]['id']);

我使用的脚本:https://github.com/SSilence/php-imap-client

我该怎么做?

查看描述,这些函数似乎没有办法限制收集的消息数量,因为它们使用消息的ID而不仅仅是一般计数。因此,您可能拥有不同的ID列表。拿他们的示例转储,你有ID 15和ID 14.列表中的下一个可能是ID 10,因为用户可能删除了13,12和11。

所以你可以收集初始列表,然后用$imap->getMessage($id);迭代它。它看起来像这样:

$overallMessages = $imap->countMessages();
$unreadMessages = $imap->countUnreadMessages();

$limitCount = 20;
$partialEmailIdList = array();

// fetch all messages in the current folder
$emails = $imap->getMessages($withbody = false);

if($limitCount < $overallMessages){
    for($i=0; $i<$limitCount; $++){
        // Populate array with IDs
        $partialEmailIdList[] = $emails[$i]['id'];
    }
} else {
    foreach($emails as $email){
        $partialEmailIdList[] = $email['id'];
    }
}
foreach($partialEmailIdList as $mid){
        $message = $imap->getMessage($mid);
        // Do stuff...
}
