Example of PHP using the Mail_MimeDecode class to extract email information_PHP tutorial

The focus is on the one_mail function. Use the Mail_mimeDecode class to extract the email header and email body from the email.

Copy code The code is as follows:

header("content-type:text/html; charset=UTF-8");

* record kid words and insert into database
* user by sending email to publication kid words
