On Windows, PEAR is included in current PHP releases (> PHP 5.2). Look for a file named "go-pear.bat". Execute this file and follow the intructions.

Notes:

If you don't have PEAR bundled with you PHP try the following alternative to install PEAR.

Download go-pear ...

> php -r "readfile('http://pear.php.net/go-pear');" > go-pear

... and install PEAR:

> php -q go-pear
