本文实例讲述了php简单实现发送带附件的邮件。分享给大家供大家参考。具体如下：
下面是静态html代码：
<html> <head> <title>带附件的邮件发送</title> </head> <body> <form method="post" name="form1" action="sendmail.php" ENCTYPE="multipart/form-data"> <table> <tr> <td>发送人：</td> <td><input type="text" name="from"></td> </tr> <tr> <td>收件人：</td> <td><input type="text" name="to"></td> </tr> <tr> <td>邮件主题：</td> <td><input type="text" name="subject"></td> </tr> <tr> <td>邮件内容：</td> <td><textarea name="body"></textarea></td> </tr> <tr> <td>附件上传：</td> <td><input type="file" name="upload_file"></td> </tr> <tr> <td span=2> <input type="submit" value="提交"> <input type="reset" value="重置"> </td> </tr> </table> </form> </body> </html>
sendmail.php文件代码：
<?php //获得表单信息 $from = $_POST['from']; $to = $_POST['to']; $subject = $_POST['subject']; $body = $_POST['body']; // 定义分界线 $boundary = "345894369383"; //分界线是一串无规律的字符 //设置header $header = "Content-type: multipart/mixed; boundary= $boundary/r/n"; $header .= "From:$from/r/n"; //获得上传文件的文件内容 $file = $_FILES['upload_file']['tmp_name']; //确定上传文件的MIME类型 $mimeType = $_FILES['upload_file']['type']; //获得上传文件的文件名 $fileName = $_FILES['upload_file']['name']; //读取上传文件 $fp = fopen($file, "r"); //打开文件 $read = fread($fp, filesize($file)); //读入文件 $read = base64_encode($read); //base64编码 $read = chunk_split($read); //切割字符串 //建立邮件的主体，分为邮件内容和附件内容两部分 $body = "--$boundary Content-type: text/plain; charset=iso-8859-1 Content-transfer-encoding: 8bit $body --$boundary Content-type: $mimeType; name=$fileName Content-disposition: attachment; filename=$fileName Content-transfer-encoding: base64 $read --$boundary--"; //发送邮件 并输出是否发送成功的信息 if(mail($to, $subject,$body,$header)) { echo "信件发送成功"; } else { echo "信件发送失败"; } ?>
希望本文所述对大家的php程序设计有所帮助。
