Installing PEAR on WAMP

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 php -d phar.require_hash=0 PEAR/go-pear.phar:

C:\wamp\bin\php\php5.3.0>php -d phar.require_hash=0 PEAR/go-pear.phar

Reply to “Are you installing a system-wide PEAR or a local copy?” with “local”. 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 the installation will attempt to change php.ini (it will prompt you first) so that include_path points to PEAR, it usesc:\wamp\bin\php\php5.3.0\php.ini rather than C:\wamp\bin\apache\apache2.2.11\bin\php.ini. So after php -d phar.require_hash=0 go-pear.phar concludes be sureC:\wamp\bin\apache\apache2.2.11\bin\php.ini has this line (your version numbers may differ).

You may also need to check that include_path in “c:\wamp\bin\php\php5.3.0\php.ini” also hasinclude_path=".;c:\wamp\bin\php\php5.3.0\pear", as I believe the command line version of php.exe may use this php.ini. It won’t hurt.

Restart Apache to reload the new php.ini and run phpinfo to verify the 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).

You may need to add the following environment variables to the environment.


Go to a command line prompt and type SET, to check the settings for the enviroment variables above.

A brief overview of the pear command line tool commands:

  • pear — This list all the PEAR commands.
  • pear help — This will tell you what the command does.
  • pear config-show — This shows your pear configuration.
  • pear list — This will show you the PEAR packages currently installed.
  • pear list -a — This will show you the PEAR packages currently installed in all channels.
  • pear channel-discover — This will initialize a new channel, so you can install packages from it
  • pear search — This will search for a PEAR package.
  • pear uninstall — This will uninstall a PEAR package.
  • pear uninstall — This will uninstall a PEAR package.
  • pear upgrade — This will upgrade all packages currently installed.
  • pear upgrade — This will upgrade all packages currently installed.

This example shows how to install the Doctrine 2 ORM using the pear command line tool:

pear channel-discover
pear install

After a package is installed, the documentation for the package will be in a newly created folder under C:\wamp\bin\php\php5.3.0\PEAR\docs\.
The C:\wamp\bin\php\php5.3.0\PEAR\test\ folder typically contains a sample test php script, to test the package.

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 install PEAR_Frontend_Web
