During this round of questions, you will also be prompted as to whether
the six optional default packages should be installed. It??™s presently an all-or-none
CHAPTER 11 ?– PEAR 315
proposition; therefore, if you??™d like to immediately begin using any of the packages,
just go ahead and accede to the request.
?– Note While the PEAR upgrade as of version 5.1. necessitates a slight change to the installation
process on Unix/Linux systems, no change is necessary for Windows, although PHP 5.1??™s Windows port
also includes the upgrade.
For the sake of convenience, you should also append the PHP installation directory
path to the PATH environment variable so the PEAR command can be easily executed.
At the conclusion of the installation process, a registry file named PEAR_ENV.reg
is created. Executing this file will create environment variables for a number of
PEAR-specific variables. Although not critical, adding these variables to the system path
affords you the convenience of executing the PEAR Package Manager from any location
while at the Windows command prompt.
?– Caution Executing the PEAR_ENV.reg file will modify your system registry. Although this particular
modification is innocuous, you should nonetheless consider backing up your registry before executing
the script. To do so, go to Start ??¤ Run, execute regedit, and then export the registry via File ??¤ Export.
