imap_bodystruct（）或imap_fetchstructure（）应该将此信息返回给您。以下代码可以完全满足您的需求：
<?php$hostname = '{********:993/imap/ssl}INBOX';$username = '*********';$password = '******';$inbox = imap_open($hostname,$username,$password) or die('Cannot connect to server: ' . imap_last_error());$emails = imap_search($inbox,'ALL');if($emails) { $output = ''; rsort($emails); foreach($emails as $email_number) { $overview = imap_fetch_overview($inbox,$email_number,0); $structure = imap_fetchstructure($inbox, $email_number); if(isset($structure->parts) && is_array($structure->parts) && isset($structure->parts[1])) { $part = $structure->parts[1]; $message = imap_fetchbody($inbox,$email_number,2); if($part->encoding == 3) { $message = imap_base64($message); } else if($part->encoding == 1) { $message = imap_8bit($message); } else { $message = imap_qprint($message); } } $output.= '<div >'; $output.= '<span >From: '.utf8_depre(imap_utf8($overview[0]->from)).'</span>'; $output.= '<span >on '.utf8_depre(imap_utf8($overview[0]->date)).'</span>'; $output.= '<br /><span >Subject('.$part->encoding.'): '.utf8_depre(imap_utf8($overview[0]->subject)).'</span> '; $output.= '</div>'; $output.= '<div >'.$message.'</div><hr />'; } echo $output;}imap_close($inbox);?>
