PHP Development Basics Tutorial: Sending Email
1. PHP mail() function
The PHP mail() function is used to send emails from scripts.
Grammar:
mail(to,subject,message,headers,parameters)
##Note: PHP running mail function 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 .
##2. PHP Simple E-MailThe 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
Example: The code is as follows
<?php $to = "1264010730@qq.com"; // 郵件接收者 $subject = "參數(shù)郵件"; // 郵件標(biāo)題 $message = "Hello! 這是郵件的內(nèi)容。"; // 郵件正文 $from = "1264010730@qq.com"; // 郵件發(fā)送者 $headers = "From:" . $from; // 頭部信息設(shè)置 mail($to,$subject,$message,$headers); echo "郵件已發(fā)送"; ?>
3. PHP Mail formThrough PHP, you can The site creates a feedback form. The following example sends a text message to the specified e-mail address
Example: The code is as follows:
<html>
<head>
<meta charset="utf-8">
<title>php中文網(wǎng)(php.cn)</title>
</head>
<body>
<?php
if (isset($_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>The output is as shown on the right
Code explanation:First, check whether the email input box is filled in
If it is not filled in (such as when the page is visited for the first time), output the HTML form
If filled (after the form is filled), send an email from the form
When the form is filled out and the submit button is clicked, the page re- Loading, you can see that the email input is reset, and the message that the email was successfully sent is displayed
Note: This simple e-mail is not safe, and will be discussed in the next chapter of this tutorial. , you'll read more about the security risks in email scripts, and we'll show you how to validate user input to make it more secure.
Learning experience: Analysis of reasons for unsuccessful sending
The first example above may cause the following error message
Alarm explanation:
