Although a PEAR subdirectory is created during WAMP installation, PEAR is not included with the Wampserver. To install PEAR open a command prompt window (Start->Run->cmd. Then Enter). Go to the php executables subdirectory and run go-pear.bat:
c:\wamp\bin\php\php5.3.0>go-pear
When prompted set each directory to the following scheme (note: the php version may differ):
| 1. Installation base ($prefix) | : C:\wamp\bin\php\php5.3.0 |
| 2. Temporary directory for processing | : C:\wamp\bin\php\php5.3.0\tmp |
| 3. Temporary directory for downloads | : C:\wamp\bin\php\php5.3.0\tmp |
| 4. Binaries directory | : C:\wamp\bin\php\php5.3.0 |
| 5. PHP code directory ($php_dir) | : C:\wamp\bin\php\php5.3.0\pear |
| 6. Documentation directory | : C:\wamp\bin\php\php5.3.0\pear\docs |
| 7. Data directory | : C:\wamp\bin\php\php5.3.0\pear\data |
| 8. User-modifiable configuration files directory | : C:\wamp\bin\php\php5.3.0\pear\cfg |
| 9. Public Web Files directory | : C:\wamp\www |
| 10. Tests directory | : C:\wamp\bin\php\php5.3.0\pear\tests |
| 11. Name of configuration file | : C:\wamp\bin\php\php5.3.0\pear.ini |
| 12. Path to CLI php.exe | : C:\wamp\bin\php\php5.3.0\. |
Although go-pear.bat will change php.ini (it will prompt you first) so that include_path points to PEAR, it uses c:\wamp\bin\php\php5.3.0\php.ini rather than C:\wamp\bin\apache\apache2.2.11\php.ini. So after go-pear.bat concludes be sure C:\wamp\bin\apache\apache2.2.11\php.ini has this line (your version of apache may differ)
include_path=".;c:\wamp\bin\php\php5.3.0\pear"
Restart Apache to reload the new php.ini and run phpinfo to verify
include_path.
Change the Windows PATH environment variable to include c:\wamp\bin\php\php5.3.0 (in Windows Vista: Start->Control Panel->System and Maintenance->System->Advanced System Settings->Environment Variable. Edit the PATH system variable and add c:\wamp\bin\php\php5.3.0). Now start a Windows command prompt and type pear. It will list all the pear commands. pear list will list all PEAR packages current installed. Use pear install -o <package> to install a package ( -o will install required dependencies).
Some packages are in beta. To install them you first need to set the preferred release to beta: pear config-set preferred_state beta. Then after installing the beta package do pear config-set preferred_state stable.
PEAR_Frontend_Web package, which was in Beta when this was written, is a web-based front-end alternative to the command line PEAR package manager. To install it open a Windows command prompt and do:
c:\wamp\bin\php\php5.3.0>pear config-set preferred_state beta
c:\wamp\bin\php\php5.3.0>pear install PEAR_Frontend_Web
c:\wamp\bin\php\php5.3.0>pear config-set preferred_state stable
To use the PEAR_Frontend_Web copy <path-to-your-php-installation>\PEAR\docs\PEAR_Frontend_Web\docs\index.php.txt to \wamp\www (or a subdirectroy thereof). I renamed it to pearweb.php. So now http://localhost/pearweb.php starts the web interface (to PEAR package management). You can see the PEAR packages that are installed and install new packages.
