Configuring PEAR on Windows PEAR is the PHP Extension and Application Repository. Applications written in PHP often include references to external libraries and PEAR is a way to manage these. On Windows if PEAR hasn’t already been configured log in to the server and run go-pear.bat in the PHP directory (C:\php in this case). This adds the PEAR settings to php.ini: include_path=“.;C:\php\pear” It also creates “pear.bat” which can be used to search for and install components. For instance: pear search Requestpear install HTTP_Request If you use the Apache Web Server after running go-pear.bat it’s necessary to restart Apache (as with any other changes to php.ini).
