= How to install PEAR on windows with WAMP =

Hello, in this tutorial I will explain step by step how to install [http://pear.php.net PEAR] and some of its packages in Windows with [http://www.wampserver.com/en/ WAMP].

1. Download and install the latest version of the WAMP Server. This is the Windows AMP (Apache, MySQL & PHP) package that I use, but I do not doubt that the results will be equally satisfactory if you use another one, like [http://www.apachefriends.org/en/xampp.html XAMPP] for example.

2. During the installation, I used the default paths proposed the installer: "C:\wamp", "C:\wamp\www", etc. Although these paths will be referenced in this tutorial, feel free to alter the paths to your needs.

3. Enter "C:\wamp\php", and locate and execute the file "go-pear.bat".

4. A command prompt window will be opened with the following message; press Enter to proceed.

5. Afterward, a list of up to 10 (this length may differ on XAMPP and others) filesystem locations will be displayed. Once again press Enter.

6. Then it will ask if we want to modify '''php.ini'''; Type in the letter '''"Y"''' (in capital letters) and press Enter.

7. To view this modification check the end of the '''"php.ini"''' (located in "C:\wamp\php") and you should see:

{{{
;***** Added by go-pear
include_path=".;C:\wamp\php\pear"
;*****
}}}

8. Next you will be notified that the '''include_path''' was updated. Press Enter to continue.

9. A final message announces that a file called '''PEAR_ENV.reg''' has been created, which, upon execution, will add some '''Windows environment variables'''.

10. Enter "C:\wamp\php" and double click the file called '''"PEAR_ENV.reg"'''. When asked to confirm the addition of registry values choose '''"Yes"''' and then click '''"OK"'''.

11. In "C:\wamp\php", copy the file '''pear.bat''' to "C:\WINDOWS\system32". Alternatively you can add "C:\wamp\php" to your windows PATH environment variable to expose this file globally.

12. Next open the run dialog and type '''"cmd"''' to open a command prompt window.

13. Type '''pear''' to see all available commands and verify proper installation. If this command is unrecognized you will have to review the previous steps and repeat anything you missed.

14. Next update the '''memory_limit''' property value to 64M in php.ini. This will help php script execution. This file is found in
"C:\wamp\php\php.ini" and "C:\wamp\Apache2\bin\php.ini"; update both.

15. Now reinitiate the services/processes through WAMP.

Finally, whenever you update PEAR or some of its packages, copy '''pear.bat''' into '''system32''' to update our list of PEAR commands. This extra step can be avoided if the path to '''pear.bat''' has been added to your PATH environment variable.
