Set the doc_root directive to point at the root directory from which your
web server serves.This is likely to be
doc_root = “c:/Program Files/Apache Software Foundation/Apache2.2/htdocs”
if you are using Apache.
Choose some extensions to run.We suggest at this stage that you just get
PHP working; you can add extensions as needed.To add an extension, look
at the list under “Windows Extensions.”You will see a lot of lines such as
;extension=php_pdf.dll
To turn on this extension, you can simply remove the semicolon at the start
of the line (and do the opposite to turn it off). Note that if you want to add
more extensions later, you should restart your web server after you have
changed php.ini for the changes to take effect.
In this book, you will use php_pdflib.dll, php_gd2.dll, php_imap.dll,
and php_mysqli.dll.You should uncomment these lines.You may find that
php_mysqli.dll is missing. If so, add it as follows:
extension=php_mysqli.dll
Close and save your php.ini file.
4. If you are using NTFS, make sure the user that the web server runs as has permission
to read your php.ini file.
Adding PHP to Your Apache Configuration
You may need to edit one of Apache’s configuration files. Open the httpd.conf file in
your favorite editor.This file is typically located in the c:\Program Files\Apache
Software Foundation\Apache2.2\conf\ directory. Look for the following lines:
LoadModule php5_module c:/php/php5apache2_2.dll
PHPIniDir "c:/php/"
AddType application/x-httpd-php .php
If you don’t see these lines, add them to the file, save it, and restart your Apache server.
Testing Your Work
The next step is to start your web server and test to ensure that you have PHP working.
Create a test.php file and add the following line to it:
Make sure the file is in the document root directory (typically C:\Program
File\Apache Software Foundation\Apache2.2\htdocs; then pull it up on the browser,
as follows:
http://localhost/test.php
