Getting the manager

Unix/Linux/BSD

When using PHP >= 4.3.0, the PEAR Package Manager is already installed unless one has used the ./configure option --without-pear.

If one uses a version of PHP that is supplied by Unix/Linux/BSD distributors it may be necessary to manually install PEAR. Users should consult the documentation for the respective distribution in this case.

For all versions prior to 4.3.0 or if you want to re-install the Package Manager, you can use the following provisional way:

$ lynx -source http://go-pear.org/ | php
      

Windows

After you have downloaded and installed PHP, you have to manually execute the batch file located in e.g. c:\php\go-pear.bat. The setup will ask you some questions and afterwards the PEAR Package Manager will be installed in the path, which you have specific during installation. Finally you have to add that installation path to your PATH environment. Either do this manually (Start > Control Panel > System > Environment) or run (double-click) the newly generated PEAR_ENV.reg that's now found in the PHP source directory. After that you can access the PEAR Package Manager by running the command pear in a Windows Command Prompt.

To update your PEAR installation from go-pear.org, request http://go-pear.org/ in your browser and save the output to a local file go-pear.php. You can then run

php go-pear.php
      
in a Windows Command Prompt to start the update process.

PEAR in hosting environments

If you are running your site at a web hosting provider with no direct access to the server (via local logins, Telnet or SSH), you can't use the PEAR Installer unless you are using PEAR_RemoteInstaller and have ftp access (sftp access is not yet supported).

Warning

FTP as a protocol is inherently insecure, as passwords are sent unencrypted.

If you are customer of a smart web hosting company, the chances are very well that the most commonly used PEAR packages are already installed on the machine that is hosting your site. If that is not the case or if you need additional packages, you should contact your provider and ask them nicely to install the package. If they refuse to do so, you can either look for a new web hosting company or you can install the package manually.
