How the tools work together

When you click the link that opens the web page with the list of released documents:

  • 1.

    A request from the web page (containing PHP code) is sent from your computer to the remote computer (which hosts the website and stores the database).

  • 2.

    The Apache web server says, “oh, here’s some PHP”, and passes it to the PHP engine.

  • 3.

    The PHP engine processes the PHP code, and sends commands to MySQL, asking for a list of the documents that is stored in the database.

  • 4.

    The MySQL server responds, pulls out the list, and hands it off to the PHP engine.

  • 5.

    The PHP code runs its course, writes the HTML web page with the document list, and hands

6.

the web page off to the Apache web server. Apache sends the HTML web page off to your browser and you read the document list.

Installing the tools

  • You can download these open-source tools from the Internet for free.

  • Each tool comes with a configuration file you edit to set it up for your own needs.

  • You don’t need to know what you are doing if you can follow directions carefully, and you use

the directions found in PHP for Dreamweaver 8, by David Powers.

  • You can also download an integrated suite, but these are more difficult to upgrade, and edit.

You will probably also find that the tools are out-of-date.
