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
|
Note: Some Linux distributions (e.g. Redhat) seem to be using links instead of lynx as the name for their command line browser. If this is the case for you, you need to change the above line correspondingly.
Note: You can also save http://go-pear.org/ as go-pear.php and run it with:
php go-pear.php
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
|
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 use the PEAR Installer using the Web Frontend.
Go to http://go-pear.org/ and save as go-pear.php. Copy go-pear.php to your server and open the corresponding URL in your browser, for example http://example.com/pear/go-pear.php.

Do not forget to protect the pear directory if you did not do already before the installation. |
