PHP Beginner's Introduction to Email

PHP mail() function

PHP mail() function is used to send an email from a script.

Syntax

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

to ?????????????????????????????????????????. Specify email recipients. ?

subject ? Required. Specifies the subject of the email. Note: This parameter cannot contain any newline characters. ?

message ? Required. Define the message to be sent. LF (\n) should be used to separate lines. Each line should be limited to 70 characters. ?

headers ? Optional. Specifies additional headers, such as From, Cc, and Bcc. Additional headers should be separated using CRLF (\r\n).

parameters Optional. Specifies additional parameters for the mailer.

Note: Running mail functions in PHP requires an installed and running mail system (such as sendmail, postfix, qmail, etc.). The program used is defined through configuration settings in the php.ini file. Read more in our PHP Mail Reference Manual .

PHP Simple E-Mail

The easiest way to send email via PHP is to send A text email.

In the following example, we first declare the variables ($to, $subject, $message, $from, $headers), and then we use these variables in the mail() function to send an E -mail:

<?php
$to = "someone@example.com";         // 郵件接收者
$subject = "參數(shù)郵件";                // 郵件標題
$message = "Hello! 這是郵件的內(nèi)容。";  // 郵件正文
$from = "someonelse@example.com";   // 郵件發(fā)送者
$headers = "From:" . $from;         // 頭部信息設置
mail($to,$subject,$message,$headers);
echo "郵件已發(fā)送";
?>

PHP Mail Form

With PHP, you can create a feedback form on your site. The following example sends a text message to the specified e-mail address:

<html>
<head>
<meta charset="utf-8">
<title>php中文網(wǎng)(php.cn)</title>
</head>
<body>

<?php
if (isset($_REQUEST['email'])) { // 如果接收到郵箱參數(shù)則發(fā)送郵件
	// 發(fā)送郵件
	$email = $_REQUEST['email'] ;
	$subject = $_REQUEST['subject'] ;
	$message = $_REQUEST['message'] ;
	mail("someone@example.com", $subject,
	$message, "From:" . $email);
	echo "郵件發(fā)送成功";
} else { // 如果沒有郵箱參數(shù)則顯示表單
	echo "<form method='post' action='mailform.php'>
	Email: <input name='email' type='text'><br>
	Subject: <input name='subject' type='text'><br>
	Message:<br>
	<textarea name='message' rows='15' cols='40'>
	</textarea><br>
	<input type='submit'>
	</form>";
}
?>

</body>
</html>
