What is the mail() Function? （Mail ()函数是什么？）

The mail() function in PHP is a built-in function that is used to send email messages from a PHP script. This function requires a few parameters to be set, including the recipient email address, the subject of the email, and the message itself. （PHP中的mail ()函数是一个内置函数，用于从PHP脚本发送电子邮件。此功能需要设置一些参数，包括收件人电子邮件地址、电子邮件的主题和消息本身。）

How to Use the mail() Function （如何使用mail ()函数）

Using the mail() function in PHP is relatively straightforward. Here is an example of how to use the function:

<?php
$to = '[email protected]';
$subject = 'Test email';
$message = 'This is a test email from PHP';

// Additional headers
$headers = 'From: [email protected]' . "\r\n" . 'Reply-To: [email protected]' . "\r\n" . 'X-Mailer: PHP/' . phpversion();

// Send the email using the mail() function
mail($to, $subject, $message, $headers);
?>

In this example, we set the recipient email address, the subject of the email, and the message itself as variables. We also set additional headers for the email, such as the sender’s email address and the X-Mailer header. Finally, we call the mail() function with these parameters to send the email. （在此示例中，我们将收件人电子邮件地址、电子邮件的主题以及邮件本身设置为变量。我们还为电子邮件设置了其他标头，例如发件人的电子邮件地址和X-Mailer标头。最后，我们使用这些参数调用mail ()函数来发送电子邮件。）
