Testing Your Installation

The simplest way to test your PHP installation is to create a small test script utilizing the phpinfo() function. This function will produce a long list of configuration information. Open a text editor and type the following line:

<?php phpinfo(); ?>

Save this file as phpinfo.php and place it in the document root of your Web serverthe htdocs subdirectory of your Apache installation, or the /Library/WebServer/Documents directory on Mac OS X. Access this file via your Web browser and you should see something like Figure 4.4, Figure 4.5, or Figure 4.6.
