Example of sending HTML email using mail function in php

PHP comes with the mailbox sending function mail(). We can use this function directly to send emails. Below I will introduce some commonly used examples of email sending. The simplest one is the mail function.

For example, the code is as follows:

function send_mail($from, $to, $subject, $message)

{

if ($from == "")

{

$from = 'Memories of the Future' ';//Sender address

}//Open source software: phpfensi.com

$headers = 'MIME-Version: 1.0' . "rn";

$headers .= 'Content- type: text/html; charset=gb2312' . "rn";

$headers .= 'From: ' . $from . "rn";

mail($to, $subject, $message, $headers);

}

?>

Tips: The program to be used is defined by the configuration settings in the php.ini file. The behavior of the mail function is affected by php.ini. We must configure it first.
