这篇文章主要介绍了php实现的发送带附件邮件类,是php程序设计中非常常见的实用技巧,实例演示了邮件类及对应的demo示例,需要的朋友可以参考下 本文实例讲述了php实现的发送带附件邮件类的方法，是一个非常实用的功能。分享给大家供大家参考。具体方法如下： emailclass.php类文件如下： <? class CMailFile { var $subject; var $addr_to; var $text_body; var $text_encoded; var $mime_headers; var $mime_boundary = "--==================_846811060==_"; var $smtp_headers; function CMailFile($subject,$to,$from,$msg,$filename,$downfilename,$mimetype = "application/octet-stream",$mime_filename = false) { $this->subject = $subject; $this->addr_to = $to; $this->smtp_headers = $this->write_smtpheaders($from); $this->text_body = $this->write_body($msg); $this->text_encoded = $this->attach_file($filename,$downfilename,$mimetype,$mime_filename); $this->mime_headers = $this->write_mimeheaders($filename, $mime_filename); } function attach_file($filename,$downfilename,$mimetype,$mime_filename) { $encoded = $this->encode_file($filename); if ($mime_filename) $filename = $mime_filename; $out = "--" . $this->mime_boundary . "n"; $out = $out . "Content-type: " . $mimetype . "; name="$filename";n"; $out = $out . "Content-Transfer-Encoding: base64n"; $out = $out . "Content-disposition: attachment; filename="$downfilename"nn"; $out = $out . $encoded . "n"; $out = $out . "--" . $this->mime_boundary . "--" . "n"; return $out; } function encode_file($sourcefile) { if (is_readable($sourcefile)) { $fd = fopen($sourcefile, "r"); $contents = fread($fd, filesize($sourcefile)); $encoded = chunk_split(base64_encode($contents)); fclose($fd); } return $encoded; } function sendfile() { $headers = $this->smtp_headers . $this->mime_headers; $message = $this->text_body . $this->text_encoded; mail($this->addr_to,$this->subject,$message,$headers); } function write_body($msgtext) { $out = "--" . $this->mime_boundary . "n"; $out = $out . "Content-Type: text/plain; charset="us-ascii"nn"; $out = $out . $msgtext . "n"; return $out; } function write_mimeheaders($filename, $mime_filename) { if ($mime_filename) $filename = $mime_filename; $out = "MIME-version: 1.0n"; $out = $out . "Content-type: multipart/mixed; "; $out = $out . "boundary="$this->mime_boundary"n"; $out = $out . "Content-transfer-encoding: 7BITn"; $out = $out . "X-attachments: $filename;nn"; return $out; } function write_smtpheaders($addr_from) { $out = "From: $addr_fromn"; $out = $out . "Reply-To: $addr_fromn"; $out = $out . "X-Mailer: PHP3n"; $out = $out . "X-Sender: $addr_fromn"; return $out; } } /*用法 - 例如:mimetype 为 "image/gif" $mailfile = new CMailFile($subject,$sendto,$replyto,$message,$filename,$mimetype); $mailfile->sendfile(); $subject -- 主题 $sendto -- 收信人地址 $replyto -- 回复地址 $message -- 信件内容 $filename -- 附件文件名 $downfilename -- 下載的文件名 $mimetype -- mime类型 */ ?> Demo示例文件如下： <?php require_once('emailclass.php'); //发送邮件 //主題 $subject = "test send email"; //收件人 $sendto = 'abc@163.com'; //發件人 $replyto = 'cdf@163.com'; //內容 $message = "test send email content"; //附件 $filename = 'test.jpg'; //附件類別 $mimetype = "image/jpeg"; $mailfile = new CMailFile($subject,$sendto,$replyto,$message,$filename,$excelname,$mimetype); $mailfile->sendfile(); ?> 相信本文所述对大家php程序设计的学习有一定的借鉴价值。 （编辑：梅州站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
