Getting and installing the PEAR package manager

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 specified 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, request http://pear.php.net/go-pear.phar in your browser and save the output to a local file go-pear.phar. You can then run

php go-pear.phar

in a Windows Command Prompt to start the update process.

After changing php.ini, you need to restart your web server.

Unix/Linux/BSD

When using PHP, 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.

If you want to re-install the Package Manager, you can use the following provisional way:

$ wget http://pear.php.net/go-pear.phar
$ php go-pear.phar
