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 = $out . "Content-Transfer-Encoding: base64\n";$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：
<?phprequire_once('emailclass.php');//发送邮件//主題$subject = "test send email";//收件人$sendto = '[email protected]';//發件人$replyto = '[email protected]';//內容$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。
