This book puts together information on installing, setting up, and troubleshooting each of the technologies (Apache, MySQL, PHP3, and IMP) into one complete volume. You also learn how each piece is part of a whole by learning, step-by-step, how to create a web-based e-mail system. Learn to run the Linux equivalent of Active Server Pages (ASP) using PHP3, set up an e-commerce site using a database and the Apache web server, and create a data entry system (such as sales, product quality tracking, customer preferences, etc) that requires no installation in the PC. This book integrates the technologies of MySQL, Apache, PHP3, and IMP into one cohesive source for developing and implementing Internet databases and email servers. Learn how to create secure Web-based email services with inexpensive open source tools (similar to Hotmail or Netscape Webmail) "from scratch" while you are taught the technologies. This book shows how MySQL, PHP, Apache, and IMP work together.
