定義和用法

mail()函數允許您從腳本中直接發送電子郵件。

如果郵件的投遞被成功地接收，則返回true，否則返回false。

語法

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

參數       描述
至       必需。規定郵件的接收者。
學科       必需。規定郵件的主題。該參數不能包含任何換行字符。
信息       必需。規定要發送的消息。
頭       必需。規定額外的報頭，比如From，Cc以及Bcc。
參數       必需。規定sendmail程序的額外參數。
說明

在信息參數規定的消息中，行之間必須以一個LF（\ n）分隔。每行不能超過70個字符。（Windows下）當PHP直接連接到SMTP服務器時，如果在一行開頭髮現一個句號，則會被刪掉。要避免此問題，將單個句號替換成兩個句號。

<?php
$text = str_replace("\n.", "\n..", $text);
?>

實例一：發送HTML郵件

<html>
<head>
<title>Sending HTML email using PHP</title>
</head>
<body>
<?php
$to = "xyz@somedomain.com";
$subject = "This is subject";
$message = "<b>This is HTML message.</b>";
$message .= "<h1>This is headline.</h1>";
$header = "From:abc@somedomain.com \r\n";
$header = "Cc:afgh@somedomain.com \r\n";
$header .= "MIME-Version: 1.0\r\n";
$header .= "Content-type: text/html\r\n";
$retval = mail ($to,$subject,$message,$header);
if( $retval == true )
{
echo "Message sent successfully...";
}
else
{
echo "Message could not be sent...";
}
?>
</body>
</html>

實例二：發送帶附件的郵件

<?php
// request variables // important
$from=$_REQUEST["from"];
$emaila=$_REQUEST["emaila"];
$filea=$_REQUEST["filea"];
if ($filea)
{
function mail_attachment ($from , $to, $subject, $message, $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="\n\n You have recieved a new attachment message from $from";
$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
$headers .= "\nMIME-Version: 1.0\n" . "Content-Type: multipart/mixed;\n" . " boundary="{$mime_boundary}"";
$email_txt .= $msg_txt;
$email_message .= "This is a multi-part message in MIME format.\n\n" . "--{$mime_boundary}\n" . "Content-Type:text/html; charset="iso-8859-1"\n" . "Content-Transfer-Encoding: 7bit\n\n" . $email_txt . "\n\n";
$data = chunk_split(base64_encode($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: base64\n\n" . $data . "\n\n" . "--{$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"]));
