APPENDIX A ■ INSTALLING APACHE, MYSQL, PHP, AND PECL ON WINDOWS 224 the installation instructions of Apache within the appendix, place the file within the APACHE_HOME/htdocs location. Load the .php file using a browser by loading the URL http://localhost/info.php to view the PHP settings your current installed PHP installation is using.

Installing PECL PECL is a PHP extension repository containing some of the best PHP extensions available for PHP developers. They range from encryption to XML parsing, with the complete list of extensions located on its official web site, http://pecl.php.net. The majority of the extensions outlined in this book can be quickly and effortlessly installed using PECL and its command-line tool. Here, we will install PECL on Windows by initially installing PEAR, a package repository for PHP. The initial step to installing PECL is to install PEAR. PEAR, as mentioned before, is a package repository for PHP. To begin installing PEAR, you are required to have PHP installed on your system. By now you should have PHP installed in your PHP_HOME directory. Open a command-line window by typing cmd into the Start->Run… window. Once the window is open, navigate into the directory where you have PHP installed, and type in php go-pear.bat. This will install PEAR as well as PECL for you. If there were no errors during APPENDIX A ■ INSTALLING APACHE, MYSQL, PHP, AND PECL ON WINDOWS 225 installation, PECL should now be installed. To verify the installation, type pecl into the command-line window. You should see the help menu, as shown in Figure A–21. Figure A–21.
