在我在 xampp 上的 codeigniter 项目中，我有这个库Imap
当我调用此函数时<?php echo $this->imap->get_mailbox_size();?>，出现此错误
地址末尾的意外字符：<> (errflg=3)
这是vardump
int(471858)
我可以很好地接收电子邮件似乎与 foreach 循环有关$messages
public function get_mailbox_size()
{
$messages = $this->get_messages();
$count = 0;
foreach($messages as $key => $value)
{
$count += $value['size'];
}
return $count;
}
问题：我不确定它的原因是什么，我该如何解决它？
