Go directly to the code:
"; if (preg_match('/^\./', $msg)) { array_push($ganji_mails, $item); break; } } continue; } $mail_content = ''; $array_ganji_mails = array(); //逐行遍历 foreach ($ganji_mails as $item) { fwrite($sock, "RETR $item\r\n"); while (true) { $msg = fgets($sock); $mail_content .= $msg; if (preg_match('/^\./', $msg)) { array_push($array_ganji_mails, iconv_mime_decode_headers($mail_content, 0, "UTF-8")); $mail_content = ''; break; } } } // 直接获取第一封邮件全部信息 9999长度 fwrite($sock, "RETR 1\r\n"); $mail_contents = fread($sock, 9999); // 直接获取全部 echo "
"; var_dump($mail_contents); echo "
"; $command = "QUIT\r\n"; fwrite($sock, $command); $msg = fgets($sock); return $mail_contents; }
