This email sending function uses a foreign open source code email class.
Things to note:
1, Mail character set setting, $mail->CharSet = "GB2312"; Specify the character set here! Here I only specify GB2312 because this way Outlook can display the email subject normally. I have tried setting it to utf-8 but it displays garbled characters in Outlook.
2. If you are sending an email in html format, remember to also specify <meta ... charset=GB2312">
3. If you want to use it to send mass emails, remember to modify the include file function, such as:
require("phpmailer/class.phpmailer.php");
Change to: require_once("phpmailer/class.phpmailer.php"); Otherwise, the class will be redefined.
