Example of sending email with attachments implemented by php

This article mainly introduces the mail class with attachments implemented by php, which is a very common practical skill in php programming. The example demonstrates the mail class and corresponding demo examples, for more information about how to send emails with attachments, see the example in this article. Share it with you for your reference. The specific method is as follows:

The emailclass. php class file is as follows:

<? 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_smtphea Ders ($ 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"; $ out = $ out. $ encoded. "\ n"; $ out = $ out. "--". $ this-> mime_boundary. "--". "\ n"; return $ out;} function encode_file ($ sourcefile) {if (is_readable ($ source File) {$ 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"; $ 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. "Conte Nt-transfer-encoding: 7BIT \ n "; $ out = $ out. "X-attachments: $ filename; \ 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 ;}/ * usage-for example, if mimetype is set to "image/gif" $ mailfile = new CMailFile ($ subject, $ sendto, $ replyto, $ message, $ filename, $ m Imetype); $ mailfile-> sendfile (); $ subject -- topic $ sendto -- recipient address $ replyto -- Reply address $ message -- Mail content $ filename -- attachment file name $ downfilename -- file name of the lower-end region $ mimetype -- mime type */?>

The Demo file is as follows:

<? Php require_once ('emailclass. php '); // send email // subject $ subject = "test send email"; // recipient $ sendto = 'ABC @ 163.com '; // sender $ replyto = 'cdf @ 163.com '; // content $ message = "test send email content"; // attachment $ filename = 'test.jpg '; // attachment type $ mimetype = "image/jpeg"; $ mailfile = new CMailFile ($ subject, $ sendto, $ replyto, $ message, $ filename, $ excelname, $ mimetype); $ mailfile-> sendfile ();?>

I believe this article provides some reference value for php programming.
