392 CHAPTER 22 LEOPARD AS A WEB SERVER PHP NOTE While disabling the explicit permissions on a user directory will do the job in a roundabout way, the proper way to enable or disable users is with the UserDir directive. See the Apache documents for more information. Whenever you change Apache’s configuration file, you will need to restart Apache. The easiest way to do this is with Terminal, using the special Apache control program, apachectl. sudo apachectl -k graceful This will restart Apache gracefully, which is to say, it will let it finish what it’s doing, shut down, and then restart. If you try to restart Apache, but it’s not already running for some reason, it will just start. If you’ve messed up the configuration file it will usually let you know on restart. Otherwise, you should be ready to test your changes. There have been a number of schemes to create dynamic web pages since the Web first came into being in 1993. Some of these rely on the client to execute. Most notable in this regard are Dynamic HTML (DHTML) and its modern equivalent, Ajax. While it’s beginning to recover, client-side scripting has traditionally been hampered by compatibility issues in the aftermath of the browser wars. Server-side scripting schemes include CGI and Server Side Includes (SSI). However, both of these have been largely rendered obsolete by PHP. Unlike CGI and SSI, PHP is a hypertext preprocessor. That is to say, it’s a page that runs a script, but ultimately serves plain HTML. Since it is open source, PHP is the preprocessor of choice on UNIX systems running Apache. Indeed, PHP has been implemented as an Apache module, and comes installed, but not activated, by default on Mac OS X. To properly ensure PHP is installed, we need to have a PHP page. The best test page is a simple PHP Info page. It relies on PHP to be working, so it’s a good test, and it gives us a lot of information about our PHP installation, so it’s actually useful. Create a PHP Info page in your favorite text editor, and save it to your document root as index.php. All you need to include is a single call to PHP’s built-in phpinfo function: Then, load the page in your browser of choice by pointing to http://127.0.0.1/index.php. You have to point to the page explicitly, because otherwise you’ll get the default index page, index.html. NOTE You can, of course, also save the PHP info page to your home Sites directory. Loading the page in your browser, you’re greeted with the entirety of its source, as written. That’s because Apache doesn’t know what a .php file is, so it’s serving it as its default MIME type, text/plain. To enable PHP, we simply need to uncomment a single line of text from the Apache configuration file. #LoadModule php5_module libexec/apache2/libphp5.so Since it starts with #, it’s a comment and is ignored. Delete the # and save. Back in the day, we’d also have to tell Apache how to handle the file type and look for index.php by default, but
all that stuff is now handled automatically by the included php5.conf file. Just restart Apache and, as the saying goes, there is no step 3. The PHP Info screen should now display properly, as shown in Figure 22-6. Figure 22-6. PHP Info page in Safari Examining the PHP Info page will tell you a lot about how your server is set up. It’s a good idea to run it on both your local machine and your remote host, so you can be aware of any differences between versions, features, or configuration options that might affect you. To learn more about PHP, including an extensive manual with installation and integration guides, visit PHP’s official web site at www.php.net/. Database Traditionally, a web server consists of four components. There’s the operating system, the web server daemon, the scripting engine, and the database server. Mac OS X, Apache, and PHP cover three of those four out of the box. Whether the database requires any additional work depends on your needs. SQLite CHAPTER 22 LEOPARD AS A WEB SERVER 393 Mac OS X Leopard comes with SQLite installed and running. SQLite is a fast, simple, lightweight database that is quickly gaining popularity with web developers. It’s compatible with the same Structured Query Language (SQL) used by nearly every other database in the world. More importantly, it’s directly addressable from PHP.
