Part I: Getting Up and Running with PHP
Now press Enter. If all has gone according to plan, you should see something like Figure 2-10 .

Figure 2-10

If your Apache server is not running on the standard HTTP port (80) — for example, if you installed
MAMP and used its default port of 8888 — modify your URL appropriately; for example: http://
localhost:8888/testing.htm l.

This means that Apache is up and running, and you ’ ve successfully located the Web server ’ s document
root. If you don ’ t get this page, it ’ s likely that one of two things is happening:

❑ If you get a 404 Not Found error, this means that the testing.html file is not in the Web
server ’ s document root. Double - check the location of the document root folder — take a look at
the documentation if necessary — and make sure your testing.html file is inside the folder.
❑ If you get a Connection Refused error, the Apache Web server is not running (or it ’ s running
on a different port). Check that you ’ ve started the Web server, and that it ’ s configured correctly
(again, the documentation that came with the package should help here).

Testing PHP
Now that you know Apache is working correctly, it ’ s time to make sure PHP is installed and working.
This is where you get to write your very first PHP script!

Open your text editor again, and create a new file with the following contents:

< ?php
phpinfo();
? >

Save this file as testing.php in the same folder as your testing.html file — that is to say, the
document root folder. Now type the following into your Web browser ’ s address bar (adjusting the HTTP
port number if necessary):

http://localhost/testing.php

Press Enter, and you should see a page similar to Figure 2-11 appear. (If you ’ ve installed PHP 5.3 you will,
of course, see references to version 5.3 in your page, rather than version 5.2.) This is the result of running
the phpinfo() function, a built - in PHP function that displays information about the version of PHP
that ’ s installed. This means that you have successfully installed both Apache and PHP. Congratulations!
