read email messages from inbox with php every 15 seconds or so

[quassi]

I'm trying to figure out a way to do the following with php:Have a website (index.php) check an e-mail inbox every 15 seconds or so, read the subject line, and the contents of the message, and then display that message on the screen. The idea being it will display all the messages in the inbox on the index.php page as they get sent in. And I guess the index.php page will also have to refresh whenever there is a new message to display the content. Thanks!
