Preparing Your Working EnvironmentAfter installing Apache 2, make sure it works OK. If you installed it on port 80, browse tohttp://localhost/. If you installed it on 8080, go to http://localhost:8080/. You should seean Apache welcome message similar to this:Figure A.2: Apache Installed SuccessfullyInstalling MySQLThe official website of MySQL is http://www.mysql.com. At the time of this writing the lateststable version is MySQL 5.0, and you can download it from http://dev.mysql.com/downloads/mysql/5.0.html. However, it's good to know that we made our SQL queries compliant with theSQL 92 standard, so you should be able to reuse them with other database systems with minimumof translation effort.In the Downloads page, scroll down to the Windows downloads section, and download theWindows Essentials file. You'll be asked to choose a mirror site, and the file will be namedsomething like mysql-essential-5.0.xx-win32.msi. After downloading the file, simply executeit to install your MySQL Server.After installation you'll be given the chance to configure your server. Do so. It's safe to use thedefault options all the way through. At some point you'll need to set the root password, which willcorrespond to the root@localhost user. Choose a password that's complicated enough for othersnot to guess and simple enough for you to remember.258
Before going through any case studies in this book, remember to see the Preparing the AJAXDatabase section at the end of this appendix.Appendix AInstalling PHPThe official website of PHP is http://www.php.net. Start by downloading from the WindowsBinaries section the latest PHP 5 zip package (not the installer!) from http://www.php.net/downloads.php. We prefer not to use the installer because it doesn't include extensions that youmay need for your projects, and it doesn't do much configuration work for you anyway.After you download the Windows binaries, follow these steps to install PHP:1. Unzip the zip package (it should be a file with a name like php-5.x.y-win32.zip) into afolder named C:\PHP\. You can choose another name or location for this folder if you want.2. Copy php.ini-recommended from C:\PHP\ to your Windows folder (C:\Windows),renaming it as php.ini.3. Open php.ini for editing with the text editor of your choice (such as Notepad) anduncomment the php_gd2.dll,php_mysql.dll, and php_xsl.dll extension lines (byremoving the leading semicolons), and add a similar line for php_mysqli:extension=php_gd2.dllextension=php_mysql.dllextension=php_mysqli.dllextension=php_xsl.dll4. We recommend enabling full error reporting for PHP on the development machine,but this is optional (this option is the default). Be warned that this change can alterthe functionality of other scripts on your server. Find the error_reporting line inphp.ini and change it to:error_reporting = E_ALL5. Copy php5ts.dll and libmysql.dll located in C:\PHP\, to the Windows System32folder (by default \Windows\System32).6. Copy php_mysql.dll, php_mysqli.dll, php_xsl.dll, and php_gd2.dll fromC:\PHP\ext, to the Windows System32 folder.7. Open the Apache configuration file for editing. By default, the location of this file isC:\Program Files\Apache Group\Apache2\conf\httpd.conf.8. In httpd.conf, find the portion with many LoadModule entries, and add thefollowing lines:LoadModule php5_module c:/php/php5apache2.dllAddType application/x-httpd-php .php9. Also in httpd.conf, find the DirectoryIndex entry, and add index.php at the endof the line, like this:DirectoryIndex index.html index.html.var index.php10. Save the httpd.conf file, and then restart the Apache 2 service, using the ApacheService Monitor by clicking its icon in the Notification Area of the taskbar. (If youget any error at this point, make sure that you followed correctly all the previous stepsof the exercise.) If Apache restarts without generating any errors, that is a good sign.259
