定义和用法

mail() 函数允许您从脚本中直接发送电子邮件。

如果邮件的投递被成功地接收，则返回 true，否则返回 false。

语法

mail(to,subject,message,headers,parameters)

参数

描述

to

必需。规定邮件的接收者。

subject

必需。规定邮件的主题。该参数不能包含任何换行字符。

message

必需。规定要发送的消息。

headers

必需。规定额外的报头，比如 From,Cc 以及 Bcc。

parameters

必需。规定 sendmail 程序的额外参数。

说明

在 message 参数规定的消息中，行之间必须以一个 LF（n）分隔。每行不能超过 70 个字符。 （Windows 下）当 PHP 直接连接到 SMTP 服务器时，如果在一行开头发现一个句号，则会被删掉。要避免此问题，将单个句号替换成两个句号。

$text = str_replace("n.","n..",$text);

?>

实例一：发送html邮件

$to = "xyz@somedomain.com";

$subject = "This is subject";

$message = "This is HTML message.";

$message .= "

This is headline.

$header = "From:abc@somedomain.com rn";

$header = "Cc:afgh@somedomain.com rn";

$header .= "MIME-Version: 1.0rn";

$header .= "Content-type: text/htmlrn";

$retval = mail ($to,$subject,$message,$header);

if( $retval == true )

{

echo "Message sent successfully...";

}

else

{

echo "Message could not be sent...";

}

?>

实例二：发送带附件的邮件

// request variables // important

$from=$_REQUEST["from"];

$emaila=$_REQUEST["emaila"];

$filea=$_REQUEST["filea"];

if ($filea)

{

function mail_attachment ($from,$to,$attachment){

$fileatt = $attachment; // Path to the file

$fileatt_type = "application/octet-stream"; // File Type

$start = strrpos($attachment,'/') == -1 ? strrpos($attachment,'//') : strrpos($attachment,'/')+1;

$fileatt_name = substr($attachment,$start,strlen($attachment)); // Filename that will be used for the file as the attachment

$email_from = $from; // Who the email is from

$subject = "New Attachment Message";

$email_subject = $subject; // The Subject of the email

$email_txt = $message; // Message that the email has in it

$email_to = $to; // Who the email is to

$headers = "From: ".$email_from;

$file = fopen($fileatt,'rb');

$data = fread($file,filesize($fileatt));

fclose($file);

$msg_txt="nn You have recieved a new attachment message from $from";

$semi_rand = md5(time());

$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";

$headers .= "nMIME-Version: 1.0n" . "Content-Type: multipart/mixed;n" . " boundary="{$mime_boundary}"";

$email_txt .= $msg_txt;

$email_message .= "This is a multi-part message in MIME format.nn" . "--{$mime_boundary}n" . "Content-Type:text/html; charset="iso-8859-1"n" . "Content-Transfer-Encoding: 7bitnn" . $email_txt . "nn";

$data = chunk_split(base64_encode($data));

$email_message .= "--{$mime_boundary}n" . "Content-Type: {$fileatt_type};n" . " name="{$fileatt_name}"n" . //"Content-Disposition: attachment;n" . //" filename="{$fileatt_name}"n" . "Content-Transfer-Encoding: base64nn" . $data . "nn" . "--{$mime_boundary}--n";

$ok = mail($email_to,$email_subject,$email_message,$headers);

if($ok)

{

echo "File Sent Successfully.";

unlink($attachment); // delete a file after attachment sent.

}

else

{

die("Sorry but the email could not be sent. Please go back and try again!");

}

}

move_uploaded_file($_FILES["filea"]["tmp_name"],'temp/'.basename($_FILES['filea']['name']));

mail_attachment("$from","youremailaddress@gmail.com","subject","message",("temp/".$_FILES["filea"]["name"]));

}
