PHP, a scripting language designed specifically for use on the Web, is your tool for creating dynamic Web pages. Rich in features that make Web design and programming easier, PHP is in use on more than 20 million domains (according to the Netcraft survey at www.php.net/usage.php). Its popularity continues to grow, so it must be fulfilling its function pretty well. PHP stands for PHP: HyperText Preprocessor. In its early development by a guy named Rasmus Lerdorf, it was called Personal Home Page tools. When it developed into a full-blown language, the name was changed to be more in line with its expanded functionality.
The PHP language’s syntax is similar to the syntax of C, so if you have experience with C, you’ll be comfortable with PHP. PHP is actually simpler than C because it doesn’t use some of the more difficult concepts of C. PHP also doesn’t include the low-level programming capabilities of C because PHP is designed to program Web sites and doesn’t require those capabilities. PHP is particularly strong in its ability to interact with databases. PHP supports pretty much every database you’ve ever heard of (and some you haven’t). PHP handles connecting to the database and communicating with it. You don’t need to know the technical details for connecting to a database or for exchanging messages with it. You tell PHP the name of the database and where it is, and PHP handles the details. It connects to the database, passes your instructions to the database, and returns the database response to you. Technical support is available for PHP. You can join one of several e-mail discussion lists offered on the PHP Web site (www.php.net), including a list for databases and PHP. In addition, a Web interface to the discussion lists is available at news.php.net, where you can browse or search the messages.
