Configuring your PEAR setup

PEAR has a number of configuration options that you can change. Getting an overview about them is as easy as issuing a

$ pear config-show

The default settings suffice for novice users, there is rarely a need to change them when getting started. You can go on with installing packages.

Reading single values is accomplished by using config-get. The following command will show you where all the .php files of your installed pear packages reside.

$ pear config-get php_dir

Changing a value is as easy as retrieving it:

$ pear config-set preferred_state beta
config-set succeeded

When changing a config setting, it does not immediately get applied to already installed packages. This is especially true when changing variables like data_dir. Use $ pear upgrade --force to reinstall all packages in such cases.

User Notes:

Note by: ashnazg
In order to unset a config option, use '':

pear config-set http_proxy ''

That should result in "pear config-show" showing http_proxy now set to "<not set>".
