Setting Up An IMAP-Based Email Solution, part 2 - Page 3
You can test your PHP by creating the following file and putting it somewhere in your web directory space:
<? phpinfo(); ?>
Call it php_info.php3. If you access this file with a browser you should see a nice page describing the PHP compilation options, and a lot of other useful information.
Part 3 of this series will deal with SquirrelMail, and Part 4 with enabling SSL. The following week will feature a closing sidebar story regarding off-the-shelf packages that handle IMAP under UNIX systems.
