本文實例講述了php簡單實現發送帶附件的郵件。分享給大家供大家參考。具體如下：
下面是靜態html代碼：
<html> <head> <title>帶附件的郵件發送</title> </head> <body> <form method="post" name="form1" action="sendmail.php" ENCTYPE="multipart/form-data"> <table> <tr> <td>發送人：</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>郵件主題：</td> <td><input type="text" name="subject"></td> </tr> <tr> <td>郵件內容：</td> <td><textarea name="body"></textarea></td> </tr> <tr> <td>附件上傳：</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文件代碼：
<?php
//獲得表單信息
$from = $_POST['from'];
$to = $_POST['to'];
$subject = $_POST['subject'];
$body = $_POST['body'];
// 定義分界線
$boundary = "345894369383"; //分界線是一串無規律的字符
//設置header
$header = "Content-type: multipart/mixed; boundary= $boundary/r/n";
$header .= "From:$from/r/n";
//獲得上傳文件的文件內容
$file = $_FILES['upload_file']['tmp_name'];
//確定上傳文件的MIME類型
$mimeType = $_FILES['upload_file']['type'];
//獲得上傳文件的文件名
$fileName = $_FILES['upload_file']['name'];
//讀取上傳文件
$fp = fopen($file, "r"); //打開文件
$read = fread($fp, filesize($file)); //讀入文件
$read = base64_encode($read); //base64編碼
$read = chunk_split($read); //切割字符串
//建立郵件的主體，分為郵件內容和附件內容兩部分
$body = "--$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--";
//發送郵件 並輸出是否發送成功的信息
if(mail($to, $subject,$body,$header))
{
echo "信件發送成功";
}
else
{
echo "信件發送失敗";
}
?>
希望本文所述對大家的php程序設計有所幫助。
