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：
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 = $out . content-transfer-encoding: base64\n;$out = $out . content-disposition: attachment; filename=\$downfilename\\n\n;$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 = $out . content-type: text/plain; charset=\us-ascii\\n\n;$out = $out . $msgtext . \n;return $out;}function write_mimeheaders($filename, $mime_filename) {if ($mime_filename) $filename = $mime_filename;$out = mime-version: 1.0\n;$out = $out . content-type: multipart/mixed; ;$out = $out . boundary=\$this->mime_boundary\\n;$out = $out . content-transfer-encoding: 7bit\n;$out = $out . x-attachments: $filename;\n\n;return $out;}function write_smtpheaders($addr_from) {$out = from: $addr_from\n;$out = $out . reply-to: $addr_from\n;$out = $out . x-mailer: php3\n;$out = $out . x-sender: $addr_from\n;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：
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。
