发布时间:2017-08-01   编辑:www.jquerycn.cn
分享一个php实现的发送带附件邮件的类,各种常用的功能都封装成了具体的方法,并附有演示示例,有需要的朋友参考下。

1,类文件 emailclass.php
 

复制代码 代码示例:
<?
/**
* 发送带附件的邮件
* by www.jbxue.com
*/
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
*/ 
?> 

2,演示示例 demo.php
 

复制代码 代码示例:
<?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'; 
     
    //附件类別 
    $mimetype = "image/jpeg"; 
 
    $mailfile = new CMailFile($subject,$sendto,$replyto,$message,$filename,$excelname,$mimetype);  
    $mailfile->sendfile(); 
?>
