How to install a PHP-Pear package

To work with pear packages, you must first install Php-pear. Once installed, you must find the source of the package to be installed.

The general syntax of installing a pear package

$ pear install package_source

Example. I want to install Auth pear package. I will write

$ pear install pear.php.net/Auth
WARNING: configuration download directory "/build/buildd/php5-5.3.2/pear-build-download" is not writeable.  Change download_dir config variable to a writeable dir to avoid this warning
Cannot install, php_dir for channel "pear.php.net" is not writeable by the current user

You can see some permission issues. You must be admin to install these packages or have sudo access

$ sudo pear install pear.php.net/Auth
