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).

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";         // 邮件接收者
$subject = "参数邮件";                // 邮件标题
$message = "Hello! 这是邮件的内容。";  // 邮件正文
$from = "someonelse@example.com";   // 邮件发送者
$headers = "From:" . $from;         // 头部信息设置
mail($to,$subject,$message,$headers);
echo "邮件已发送";
?>

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中文网(php.cn)</title>
</head>
<body>

<?php
if (isset($_REQUEST['email'])) { // 如果接收到邮箱参数则发送邮件
	// 发送邮件
	$email = $_REQUEST['email'] ;
	$subject = $_REQUEST['subject'] ;
	$message = $_REQUEST['message'] ;
	mail("someone@example.com", $subject,
	$message, "From:" . $email);
	echo "邮件发送成功";
} else { // 如果没有邮箱参数则显示表单
	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>
